Melanoma cells present a MAGE-3 epitope to CD4(+) cytotoxic T cells in association with histocompatibility leukocyte antigen DR11. (1/5661)

In this study we used TEPITOPE, a new epitope prediction software, to identify sequence segments on the MAGE-3 protein with promiscuous binding to histocompatibility leukocyte antigen (HLA)-DR molecules. Synthetic peptides corresponding to the identified sequences were synthesized and used to propagate CD4(+) T cells from the blood of a healthy donor. CD4(+) T cells strongly recognized MAGE-3281-295 and, to a lesser extent, MAGE-3141-155 and MAGE-3146-160. Moreover, CD4(+) T cells proliferated in the presence of recombinant MAGE-3 after processing and presentation by autologous antigen presenting cells, demonstrating that the MAGE-3 epitopes recognized are naturally processed. CD4(+) T cells, mostly of the T helper 1 type, showed specific lytic activity against HLA-DR11/MAGE-3-positive melanoma cells. Cold target inhibition experiments demonstrated indeed that the CD4(+) T cells recognized MAGE-3281-295 in association with HLA-DR11 on melanoma cells. This is the first evidence that a tumor-specific shared antigen forms CD4(+) T cell epitopes. Furthermore, we validated the use of algorithms for the prediction of promiscuous CD4(+) T cell epitopes, thus opening the possibility of wide application to other tumor-associated antigens. These results have direct implications for cancer immunotherapy in the design of peptide-based vaccines with tumor-specific CD4(+) T cell epitopes.  (+info)

Disorders in cell circuitry associated with multistage carcinogenesis: exploitable targets for cancer prevention and therapy. (2/5661)

The development of a malignant tumor involves the progressive acquisition of mutations and epigenetic abnormalities in multiple genes that have highly diverse functions. Some of these genes code for pathways of signal transduction that mediate the action of growth factors. The enzyme protein kinase C plays an important role in these events and in the process of tumor promotion. Therefore, we examined the effects of three inhibitors of protein kinase C, CGP 41251, RO 31-8220, and calphostin C, on human glioblastoma cells. These compounds inhibited growth and induced apoptosis; these activities were associated with a decrease in the level of CDC2 and cyclin B1/CDC2-associated kinase activity. This may explain why the treated cells accumulated in G2-M. In a separate series of studies, we examined abnormalities in cell cycle control genes in human cancer. We have found that cyclin D1 is frequently overexpressed in a variety of human cancers. Mechanistic studies indicate that cyclin D1 can play a critical role in carcinogenesis because: overexpression enhances cell transformation and tumorigenesis; introduction of an antisense cyclin D1 cDNA into either human esophageal or colon cancer cells reverts their malignant phenotype; and overexpression of cyclin D1 can enhance the amplification of other genes. The latter finding suggests that cyclin D1 can enhance genomic instability and, thereby, the process of tumor progression. Therefore, inhibitors of the function of cyclin D1 may be useful in both cancer chemoprevention and therapy. We obtained evidence for the existence of homeostatic feedback loops between cyclins D1 or E and the cell cycle inhibitory protein p27Kip1. On the basis of these and other findings, we hypothesize that, because of their disordered circuitry, cancer cells suffer from "gene addiction" and "gene hypersensitivity," disorders that might be exploited in both cancer prevention and therapy.  (+info)

Impaired invariant chain degradation and antigen presentation and diminished collagen-induced arthritis in cathepsin S null mice. (3/5661)

Cathepsins have been implicated in the degradation of proteins destined for the MHC class II processing pathway and in the proteolytic removal of invariant chain (Ii), a critical regulator of MHC class II function. Mice lacking the lysosomal cysteine proteinase cathepsin S (catS) demonstrated a profound inhibition of Ii degradation in professional APC in vivo. A marked variation in the generation of MHC class II-bound Ii fragments and presentation of exogenous proteins was observed between B cells, dendritic cells, and macrophages lacking catS. CatS-deficient mice showed diminished susceptibility to collagen-induced arthritis, suggesting a potential therapeutic target for regulation of immune responsiveness.  (+info)

A transfection compound series based on a versatile Tris linkage. (4/5661)

The family of cationic lipid transfection reagents described here demonstrates a modular design that offers potential for the ready synthesis of a wide variety of molecular variants. The key feature of these new molecules is the use of Tris as a linker for joining the hydrophobic domain to a cationic head group. The molecular design offers the opportunity to conveniently synthesise compounds differing in charge, the number and nature of hydrophobic groups in the hydrophobic domain and the characteristics of the spacer between the cationic and hydrophobic moieties. We show that prototype reagents of this design can deliver reporter genes into cultured cells with efficiencies rivaling those of established cationic lipid transfection reagents. A feature of these reagents is that they are not dependent on formulation with a neutral lipid for activity.  (+info)

Rational design and synthesis of a novel anti-leukemic agent targeting Bruton's tyrosine kinase (BTK), LFM-A13 [alpha-cyano-beta-hydroxy-beta-methyl-N-(2, 5-dibromophenyl)propenamide]. (5/5661)

In a systematic effort to design potent inhibitors of the anti-apoptotic tyrosine kinase BTK (Bruton's tyrosine kinase) as anti-leukemic agents with apoptosis-promoting and chemosensitizing properties, we have constructed a three-dimensional homology model of the BTK kinase domain. Our modeling studies revealed a distinct rectangular binding pocket near the hinge region of the BTK kinase domain with Leu460, Tyr476, Arg525, and Asp539 residues occupying the corners of the rectangle. The dimensions of this rectangle are approximately 18 x 8 x 9 x 17 A, and the thickness of the pocket is approximately 7 A. Advanced docking procedures were employed for the rational design of leflunomide metabolite (LFM) analogs with a high likelihood to bind favorably to the catalytic site within the kinase domain of BTK. The lead compound LFM-A13, for which we calculated a Ki value of 1.4 microM, inhibited human BTK in vitro with an IC50 value of 17.2 +/- 0.8 microM. Similarly, LFM-A13 inhibited recombinant BTK expressed in a baculovirus expression vector system with an IC50 value of 2.5 microM. The energetically favorable position of LFM-A13 in the binding pocket is such that its aromatic ring is close to Tyr476, and its substituent group is sandwiched between residues Arg525 and Asp539. In addition, LFM-A13 is capable of favorable hydrogen bonding interactions with BTK via Asp539 and Arg525 residues. Besides its remarkable potency in BTK kinase assays, LFM-A13 was also discovered to be a highly specific inhibitor of BTK. Even at concentrations as high as 100 micrograms/ml (approximately 278 microM), this novel inhibitor did not affect the enzymatic activity of other protein tyrosine kinases, including JAK1, JAK3, HCK, epidermal growth factor receptor kinase, and insulin receptor kinase. In accordance with the anti-apoptotic function of BTK, treatment of BTK+ B-lineage leukemic cells with LFM-A13 enhanced their sensitivity to ceramide- or vincristine-induced apoptosis. To our knowledge, LFM-A13 is the first BTK-specific tyrosine kinase inhibitor and the first anti-leukemic agent targeting BTK.  (+info)

Design of highly specific cytotoxins by using trans-splicing ribozymes. (6/5661)

We have designed ribozymes based on a self-splicing group I intron that can trans-splice exon sequences into a chosen RNA target to create a functional chimeric mRNA and provide a highly specific trigger for gene expression. We have targeted ribozymes against the coat protein mRNA of a widespread plant pathogen, cucumber mosaic virus. The ribozymes were designed to trans-splice the coding sequence of the diphtheria toxin A chain in frame with the viral initiation codon of the target sequence. Diphtheria toxin A chain catalyzes the ADP ribosylation of elongation factor 2 and can cause the cessation of protein translation. In a Saccharomyces cerevisiae model system, ribozyme expression was shown to specifically inhibit the growth of cells expressing the virus mRNA. A point mutation at the target splice site alleviated this ribozyme-mediated toxicity. Increasing the extent of base pairing between the ribozyme and target dramatically increased specific expression of the cytotoxin and reduced illegitimate toxicity in vivo. Trans-splicing ribozymes may provide a new class of agents for engineering virus resistance and therapeutic cytotoxins.  (+info)

A cytosine analog that confers enhanced potency to antisense oligonucleotides. (7/5661)

Antisense technology is based on the ability to design potent, sequence-specific inhibitors. The G-clamp heterocycle modification, a cytosine analog that clamps on to guanine by forming an additional hydrogen bond, was rationally designed to enhance oligonucleotide/RNA hybrid affinity. A single, context-dependent substitution of a G-clamp heterocycle into a 15-mer phosphorothioate oligodeoxynucleotide (S-ON) targeting the cyclin-dependent kinase inhibitor, p27(kip1), enhanced antisense activity as compared with a previously optimized C5-propynyl-modified p27(kip1) S-ON and functionally replaced 11 C5-propynyl modifications. Dose-dependent, sequence-specific antisense inhibition was observed at nanomolar concentrations of the G-clamp S-ONs. A single nucleotide mismatch between the G-clamp S-ON and the p27(kip1) mRNA reduced the potency of the antisense ON by five-fold. A 2-base-mismatch S-ON eliminated antisense activity, confirming the sequence specificity of G-clamp-modified S-ONs. The G-clamp-substituted p27(kip1) S-ON activated RNase H-mediated cleavage and demonstrated increased in vitro binding affinity for its RNA target compared with conventional 15-mer S-ONs. Furthermore, incorporation of a single G-clamp modification into a previously optimized 20-mer phosphorothioate antisense S-ON targeting c-raf increased the potency of the S-ON 25-fold. The G-clamp heterocycle is a potent, mismatch-sensitive, automated synthesizer-compatible antisense S-ON modification that will have important applications in the elucidation of gene function, the validation of gene targets, and the development of more potent antisense-based pharmaceuticals.  (+info)

Crystal structure of human type II inosine monophosphate dehydrogenase: implications for ligand binding and drug design. (8/5661)

Inosine monophosphate dehydrogenase (IMPDH) controls a key metabolic step in the regulation of cell growth and differentiation. This step is the NAD-dependent oxidation of inosine 5' monophosphate (IMP) to xanthosine 5' monophosphate, the rate-limiting step in the synthesis of the guanine nucleotides. Two isoforms of IMPDH have been identified, one of which (type II) is significantly up- regulated in neoplastic and differentiating cells. As such, it has been identified as a major target in antitumor and immunosuppressive drug design. We present here the 2.9-A structure of a ternary complex of the human type II isoform of IMPDH. The complex contains the substrate analogue 6-chloropurine riboside 5'-monophosphate (6-Cl-IMP) and the NAD analogue selenazole-4-carboxamide adenine dinucleotide, the selenium derivative of the active metabolite of the antitumor drug tiazofurin. The enzyme forms a homotetramer, with the dinucleotide binding at the monomer-monomer interface. The 6 chloro-substituted purine base is dehalogenated, forming a covalent adduct at C6 with Cys-331. The dinucleotide selenazole base is stacked against the 6-Cl-IMP purine ring in an orientation consistent with the B-side stereochemistry of hydride transfer seen with NAD. The adenosine end of the ligand interacts with residues not conserved between the type I and type II isoforms, suggesting strategies for the design of isoform-specific agents.  (+info)

Protein structure-based drug design has been contributing to the drug discovery process since the early 1990s. Structural knowledge on the exact interactions of drugs with their target proteins has been applied mainly to predict potency changes of chemically modified lead compounds.. With the 3D-structural information available today, additional aspects of the drug discovery process become predictable. Target-based virtual screening is being applied to identify new unexpected lead structures. Selectivity of compounds between homologous or orthologous proteins can be predicted, offering new possibilities to design selective compounds or predict the suitability of animal models for pharmacodynamic studies. Also the number of x-ray structures of proteins relevant for ADMET properties of drug molecules has remarkably increased during the last few years. This development offers the possibility to modulate or rationally design out unwanted ADMET properties. This covers aspects such as plasma protein ...

Structure-based drug design (SBDD) has become a powerful tool utilized by medicinal chemists to rationally guide the drug discovery process. Herein, we describe the use of SPROUT, a de novo-based program, to identify an indazole-based pharmacophore for the inhibition of fibroblast growth factor receptor (FGFR) kinases, which are validated targets for cancer therapy. Hit identification using SPROUT yielded 6-phenylindole as a small fragment predicted to bind to FGFR1. With the aid of docking models, several modifications to the indole were made to optimize the fragment to an indazole-containing pharmacophore, leading to a library of compounds containing 23 derivatives ...
A method of rational drug design includes simulating polypeptides in a way that predicts the most probable secondary and/or tertiary structures of a polypeptide, e.g., an oligopeptide, without any presumptions as to the conformation of the underlying primary or secondary structure. The method involves computer simulation of the polypeptide, and more particularly simulating a real-size primary structure in an aqueous environment, shrinking the size of the polypeptide isobarically and isothermally, and expanding the simulated polypeptide to its real size in selected time periods. A useful set of tools, termed Balaji plots, energy conformational maps, and probability maps, assist in identifying those portions of the predicted peptide structure that are most flexible or most rigid. The rational design of novel compounds, useful as drugs, e.g., bioactive peptidomimetic compounds, and constrained analogs thereof, is thus made possible using the simulation methods and tools of the described invention.

Professional bodies and Institutes CPD schemes are either structured as Input or Output based. Input based schemes list a precise number of CPD hours that individuals must achieve within a given time period. These schemes can also use different currencies such as points, merits, units or credits, where an individual must accumulate the number required. These currencies are usually based on time i.e. 1 CPD point = 1 hour of learning. Output based schemes are learner centred. They require individuals to set learning goals that align to professional competencies, or personal development objectives. These schemes also list different ways to achieve the learning goals e.g. training courses, seminars or e:learning, which enables an individual to complete their CPD through their preferred mode of learning. The majority of Input and Output based schemes actively encourage individuals to seek appropriate CPD activities independently. As a formal provider of CPD certified activities, SMI Group ...

The antiviral therapeutic area continues to rapidly generate meaningful new chemical entities; for example, for HIV alone more than 25 drugs have been approved, and in the next few years many individual drugs and single tablet regimens will be approved for the treatment of hepatitis C virus infection. The increasing success in the antiviral area could be due to targeting drugs at non-self genomes and to the patient population that is tolerant of manageable side effects and adaptable to inconvenient dosing.Aimed at medicinal chemists and emerging drug discovery scientists, the book is organized according to the various strategies deployed for the discovery and optimization of initial lead compounds. This book focuses on capturing tactical aspects of problem solving in antiviral drug design, an approach that holds special appeal for those engaged in antiviral drug development, but also appeals to the broader medicinal chemistry community based on its focus on tactical aspects of drug design.

A primary objective of our research is to design new antibacterial agents based on novel mechanisms of action. Currently, all clinically used antibiotics act by one of a limited number of mechanisms (e.g. inhibition of protein synthesis, DNA synthesis, cell-wall synthesis, and RNA transcription). We utilize available data from experimental genetic approaches to identify candidate bacterial targets. In cases where the structure and enzymology of the bacterial enzyme is known, we rationally design substrate mimics or transition-state inhibitors. However, for many potential targets there is inadequate structural information available to permit such a structure-based drug design approach. In these cases we develop high-throughput-screening (HTS) assays that allow us to identify a lead candidate molecule. Once a small molecule inhibitor is identified against the targeted enzyme we then apply medicinal chemistry efforts to methodically optimize the inhibitor scaffold. Structure- and/or ligand-based ...

Virtual screening of chemical databases to targets of known three-dimensional structure is developing into an increasingly reliable method for finding new lead candidates in drug development. Both better scoring functions and novel docking strategies contribute to this trend, although no completely satisfying approach has been established yet. This is not surprising since the approximations which are needed to achieve a reasonable screening rates impose significant restrictions on the virtual representation of the physical system. Relaxation of these restrictions, such as permitting ligand or receptor flexibility, potentially increase the reliability of the scoring process, but come at a high computational cost. While ligand flexibility is now routinely considered in many atomistic in-silico screening methods, accounting for receptor flexibility still poses significant challenges. Using the thymidine kinase inhibitors as a prototypical example we document the shortcoming of rigid receptor screens in a

The reason for the low number of successful new CNS drugs is the subject of debate, although it is undoubtedly related to their higher attrition rate during development, particularly from issues related to failures of on-target biological hypotheses. To address this problem, there has been a recent emphasis on research to tackle these issues at an earlier stage in the drug discovery pathway. In particular, there has been increased interest in target discovery both for the identification of novel targets and reducing the subsequent failure from incorrect biological hypotheses through early validation.. Target discovery, which involves the identification and early validation of disease-modifying targets, is an essential first step in the drug discovery process. Furthermore, although the knowledge of the target for a small molecule drug is not required by the FDA for drug development, it is crucial information if the drug discovery process is to be made more efficient and effective. Identifying the ...

Clumps of proteins that accumulate in brain cells are a hallmark of neurological diseases such as dementia, Parkinsons disease and Alzheimers disease. Over the past several years, there has been much controversy over the structure of one of those proteins, known as alpha synuclein.. MIT computational scientists have now modeled the structure of that protein, most commonly associated with Parkinsons, and found that it can take on either of two proposed states - floppy or rigid. The findings suggest that forcing the protein to switch to the rigid structure, which does not aggregate, could offer a new way to treat Parkinsons, says Collin Stultz, an associate professor of electrical engineering and computer science at MIT.. If alpha synuclein can really adopt this ordered structure that does not aggregate, you could imagine a drug-design strategy that stabilizes these ordered structures to prevent them from aggregating, says Stultz, who is the senior author of a paper describing the findings ...

Both docking cavities identified by the floodfill algorithm are in close vicinity to and in close contact with the earlier suggested NP epitope sequences studied in a previous study [21] (see Figure 1). Site 2 occupies an arginine-rich region of the RNA-binding groove and forms extensive contacts with another NP-conserved epitope sequence R174-K184, which makes the site very attractive for targeting NP. Meanwhile, Site 1 has only minor contact with another epitope sequence, I265-S274. Surprisingly, both Site 1 and Site 2 are distant from the proposed binding site of the recent NP inhibitor nucleozin, which is marked by the residue Y289 [17] on Figure 1.. The demonstrated level of animal protection in treatments with F66 reached 40%, which is comparable to the protection provided by treatment with rimantadine in a similar experiment (60%). In the emergency prophylaxis study, the compound application increased the lifetime of the mice by 2.7 days. The results are inferior to the protection level ...
Dear Colleagues,. The 7th Brazilian Symposium on Medicinal Chemistry (BrazMedChem2014) is going to be held at the Campos do Jordao Convention Center, in Campos do Jordao (Sao Paulo State) Brazil, from November 9 to 12, 2014.. In this edition, we envisage to keep the high scientific level that was achieved in previous editions. To accomplish with that, Brazilian and foreign scientists will get together in Campos do Jordao to discuss about the intricacies of the drug discovery process.. The running title of this edition Facing the Turning Point in Medicinal Chemistry was chosen due to the dramatic changes perceived in discovery and development of new bioactive molecules. The role of the medicinal chemist is under revision with a reposition as a response to this scenario, once medicinal chemistry plays a critical role in this area.. This event also wants to contribute to the education of undergrad and graduate students in the medicinal chemistry field, once they correspond to the majority of the ...

Over the past decades, molecular docking has become an important element for drug design and discovery. Many novel computational drug design methods were
One of the initial steps of modern drug discovery is the identification of small organic molecules able to inhibit a target macromolecule of therapeutic interest. discovery are urgently required if we are to tackle the multiple global health challenges of emerging and neglected infectious diseases for which there is relatively little basic science investment. Recently, Simmons and and [17]. This pathway is present in bacteria, fungi, plants and apicomplexan parasites, but not in mammals, and hence represents an ideal target for the development of antibacterial agents, as these agents would be expected to have a spectrum of antibacterial activity restricted to those human pathogens expressing DHQase such as and DHQase was used as a starting point to identify novel inhibitors [18]. While approximately 100 molecules with more than 50 per cent inhibition of DHQase enzyme activity at a concentration of 20 g ml?1 were identified in the primary screening, only one confirmed inhibitor against DHQase was ...

In contrast to traditional methods of drug discovery (known as forward pharmacology), which rely on trial-and-error testing of chemical substances on cultured cells or animals, and matching the apparent effects to treatments, rational drug design (also called reverse pharmacology) begins with a hypothesis that modulation of a specific biological target may have therapeutic value. In order for a biomolecule to be selected as a drug target, two essential pieces of information are required. The first is evidence that modulation of the target will be disease modifying. This knowledge may come from, for example, disease linkage studies that show an association between mutations in the biological target and certain disease states.[16] The second is that the target is druggable. This means that it is capable of binding to a small molecule and that its activity can be modulated by the small molecule.[17] Once a suitable target has been identified, the target is normally cloned and produced and ...

Recently, metabolite characterization has shifted from the development stage of the drug discovery process and has become an integral component of early discovery-stage research. Concomitant with this shift has been a change in the type of information sought from metabolic studies. Although detailed qualitative and quantitative analysis of the metabolic pathway of a lead candidate continues to be an essential element of the drug development process, biotransformation information gleaned at the discovery stage can be used to guide synthetic chemistry efforts to either block or enhance metabolism with a view to optimizing the pharmacokinetic and safety profiles of newly synthesized compounds. Additionally, data on the metabolic fate of a large number of compounds may facilitate the development of structure-activity relationships for metabolism.. The availability of tandem mass spectrometers (McLafferty, 1980; Busch et al., 1988) has given the drug metabolism scientist a very powerful tool for ...
