A transfection compound series based on a versatile Tris linkage. (1/108)

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)

Non-viral neuronal gene delivery mediated by the HC fragment of tetanus toxin. (2/108)

Many inherited neurological diseases and cancers could potentially benefit from efficient targeted gene delivery to neurons of the central nervous system. The nontoxic fragment C (HC) of tetanus toxin retains the specific nerve cell binding and transport properties of tetanus holotoxin. The HC fragment has previously been used to promote the uptake of attached proteins such as horseradish peroxidase, beta-galactosidase and superoxide dismutase into neuronal cells in vitro and in vivo. We report the use of purified recombinant HC fragment produced in yeast and covalently bound to polylysine [poly(K)] to enable binding of DNA. We demonstrate that when used to transfect cells, this construct results in nonviral gene delivery and marker gene expression in vitro in N18 RE 105 cells (a neuroblastoma x glioma mouse/rat hybrid cell line) and F98 (a glioma cell line). Transfection was dependent on HC and was neuronal cell type specific. HC may prove a useful targeting ligand for future neuronal gene therapy.  (+info)

In vitro cytotoxicity of poly(amidoamine)s: relevance to DNA delivery. (3/108)

We have examined the cytotoxicity of a number of poly(amidoamine) polymers which have been proposed for use as DNA delivery systems and compared them to the charged polyamino acid polylysine. Most of the poly(amidoamine)s tested were shown to be remarkably non-toxic to both HepG2 and HL60 cell lines. However, one of the structures (NG30, co-monomers methylene bisacrylamide, dimethylethylene diamine) did show cytotoxicity similar to that of polylysine. A second PAA structure (NG37, NG38, NG39, co-monomers bisacryloyl piperazine, 2-methyl piperazine) showed mild cytotoxicity towards both cell lines, related to the degree of polymerisation. The results support the idea that the cytotoxicity of polycations has a strong structural basis rather than being an effect due only to charge. As a consequence of their general reduced level of cytotoxicity, poly(amidoamine)s appear to have possible advantages for complexation with DNA over some other cationic polymers as a key component of DNA delivery systems.  (+info)

Oligonucleotide uptake in cultured keratinocytes: influence of confluence, cationic liposomes, and keratinocyte cell type. (4/108)

The success of anti-sense strategies has been limited, at least in part, by the poor uptake of these agents into the target cells. In keratinocytes, there is conflicting evidence as to the amount and location of oligonucleotide uptake into these cells, with variable proportions of cells reported to take up oligodeoxynucleotide, and also cytoplasmic and nuclear localization reported. In this study, the uptake of oligodeoxynucleotides in cultured normal human keratinocytes and the HaCaT cell line was quantitated in the presence of various lipids designed to enhance uptake and in varying culture conditions. About 12% of cells in a confluent normal human keratinocyte culture showed nuclear uptake, with a small and variable proportion showing cytoplasmic localization after 24 h incubation with 1 microM oligodeoxynucleotide. Uptake of oligodeoxynucleotide was found to be increased by liposome encapsulation (to a maximum of 28.1% +/- 2.1% of cells), low confluence (39.5% +/- 2.5%), and further increased by a combination of the two conditions (55.4% +/- 4.3%). HaCaT cell populations showed sparse but consistent uptake of oligodeoxynucleotide, with about 1% of cells showing nuclear localization in the presence of 1 microM oligodeoxynucleotide, increasing to 13.5% +/- 4.9% in the presence of cationic lipid (Tfx-50) in low confluence HaCaT monolayers. We conclude that normal keratinocytes exhibit reliable, substantial uptake of oligonucleotides in conditions controlled for confluence and aided by liposome encapsulation.  (+info)

Molecular correlates of the calcium-independent, depolarization-activated K+ currents in rat atrial myocytes. (5/108)

1. In adult rat atrial myocytes, three kinetically distinct Ca2+-independent depolarization-activated outward K+ currents, IK, fast, IK,slow and Iss, have been separated and characterized. 2. To test directly the hypothesis that different voltage-dependent K+ channel (Kv channel) alpha subunits underlie rat atrial IK,fast, IK, slow and Iss, the effects of antisense oligodeoxynucleotides (AsODNs) targeted against the translation start sites of the Kv alpha subunits Kv1.2, Kv1.5, Kv4.2, Kv4.3, Kv2.1 and KvLQT1 were examined. 3. Control experiments on heterologously expressed Kv alpha subunits revealed that each AsODN is selective for the subunit against which it was targeted. 4. Peak outward K+ currents were attenuated significantly in rat atrial myocytes exposed to AsODNs targeted against Kv4.2, Kv1.2 and Kv1.5, whereas AsODNs targeted against Kv2.1, Kv4.3 and KvLQT1 were without effects. 5. No measurable effects on inwardly rectifying K+ currents (IK1) were observed in atrial cells exposed to any of the Kv alpha subunit AsODNs. 6. Kinetic analysis of the currents evoked during long (10 s) depolarizing voltage steps revealed that AsODNs targeted against Kv4.2, Kv1.2 and Kv1.5 selectively attenuate rat atrial IK,fast, IK, slow and Iss, respectively, thus demonstrating that the molecular correlates of rat atrial IK,fast, IK,slow and Iss are distinct. 7. The lack of effect of the Kv4.3 AsODNs on peak outward K+ currents reveals that Kv4.2 and Kv4.3 do not heteromultimerize in rat atria in vivo. In addition, the finding that Kv1.2 and Kv1.5 contribute to distinct K+ currents in rat atrial myocytes demonstrates that Kv1.2 and Kv1.5 also do not associate in rat atria in vivo.  (+info)

Gene transfer mediated by YKS-220 cationic particles: convenient and efficient gene delivery reagent. (6/108)

A monocationic lipid, YKS-220, with a symmetrical and biodegradable structure can be used as an effective gene transfer vector in a cationic particle form (not a cationic liposome form), and is obtained by diluting an ethanol solution of YKS-220 and DOPE (1:5, molar ratio) with an aqueous medium. This preparation method is more convenient than that for cationic liposomes. YKS-220 cationic particles showed a heterogeneous large mean diameter of 4.4 microm. An obvious size change was not observed when plasmid DNA was added. The transfection activity of YKS-220 cationic particles was comparable to those of YKS-220 liposomes and DOSPA liposomes (LipofectAMINE), and even higher than that of DOGS (TRNSFECTAM). Interestingly, the YKS-220 cationic particle/DNA complexes were resistant to the neutralizing effect of serum. All of these findings indicate that YKS-220 cationic particles are a convenient and efficient gene delivery reagent.  (+info)

Differential behaviour of lipid based and polycation based gene transfer systems in transfecting primary human fibroblasts: a potential role of polylysine in nuclear transport. (7/108)

DNA delivery systems for gene therapy applications have to be able to trigger the uptake of plasmid DNA into the nucleus. We have tested two types of non-viral vector systems, lipofection (cationic lipid-based, using Lipofectamine) and polyfection (cationic polymer-based, using glycerol enhanced transferrinfection), for their ability to transfect confluent, contact inhibited primary human fibroblasts. While both systems worked well with growing fibroblasts, polyfection was superior with confluent cells. A slight reduction in cell associated plasmid DNA was observed with resting cells, but it was similar for both types of complexes. Lipofectamine showed a prevalence for transfecting cycling cells as judged by costaining transfected cells with cell cycle markers. No such bias was observed when glycerol enhanced transferrinfection was used. Microinjection of plasmid DNA/polylysine complexes into the cytoplasm of fibroblasts resulted in a higher percentage of expressing cells than injection of plasmid DNA, offering an explanation for the higher transfection levels obtained with transferrinfection in non-growing cells.  (+info)

Method of transfection affects the cAMP-mediated induction of the RIIbeta subunit of protein kinase A in Sertoli cells: inhibition of response by increase in intracellullar calcium. (8/108)

mRNA for the regulatory subunit RIIbeta of cAMP-dependent protein kinase is stimulated more than 50-fold by cAMP in primary cultures of rat Sertoli cells. We have previously shown that this induction involves regulation of transcriptional activation as well as mRNA stabilization. The rat RIIbeta gene contains no cAMP response element (CRE), and the induction of RIIbeta mRNA is slow and requires on-going protein synthesis. When a construct containing the 5'-flanking region of the RIIbeta gene upstream of a CAT reporter was transfected into Sertoli cells by the calcium phosphate method, low and variable responses to cAMP (three- to fivefold) were observed, whereas a 15- to 20-fold increase in reporter activity by cAMP was observed after lipofectamine transfection. Interestingly, when a vector containing CRE elements upstream of a reporter gene was transfected into Sertoli cells, the responses to cAMP were similar regardless of the transfection method used. We have also demonstrated that increased intracellular levels of calcium by A23187 and thapsigargin dramatically inhibit cAMP-mediated induction of RIIbeta mRNA, but not the mRNA for the CRE-containing RIalpha gene. Furthermore, decreased cAMP responsiveness of endogenous RIIbetamRNA (but not RIalpha) was also observed in calcium phosphate-transfected Sertoli cells but not in lipofectamine-transfected cells. Thus, calcium-mediated reduction in cAMP response appears to be a gene-specific phenomenon.  (+info)

Silica sols are placed in contact with a strong acid cation exchange resin. The sols are then aged out of contact with the cation exchange resin for at least about 4 hours at a temperature of from about 34 DEG F. to about the boiling point of the sols, and again contacted with a cation exchange resin. The process requires placing the sols at least twice in contact with a cation exchange resin with an aging step between each treatment, and also requires that the sols be placed at least once in contact with an anion exchange resin. The formed sols have excellent stability characteristics even at high SiO2 concentrations.

Extraction of chromium(III) from a model solution and from a tannery waste solution was studied by ion exchange using Indion 790 resin which is a macro-porous strongly acidic cation exchange resin of sulfonated polystyrene group. The resin was found to be selective for the sorption of chromium(III) in the pH range 0.5-3.5 from a model solution containing 500 ppm Cr(III). Beyond pH 3.5 extraction of chromium(III) drastically decreased from 92% to 76%. Sorption of chromium(III) on Indion 790 followed the Freundlich isotherm with a high Freundlich constant value (Kf = 8.57) confirming strong chemical interaction of the metal ion with the resin. Desorption of chromium(III) from the loaded resin increased with the increase in concentration of eluant (5-20% H2SO4). With 20% sulfuric acid solution 89% Cr(III) was eluted in two stages. The bench scale results were also validated in continuous mode in a fixed bed column and for the recovery of chromium(III) from a tannery solution ...

Three materials that are designed to treat uranium-contaminated water were investigated. These are a cation exchange resin, IRN 77; an anion exchange resin, Varion AP; and a recently developed material called PANSIL (quartz sand coated with 2% amidoxime resin by weight). The reaction rate, capacity, and effective pH range of the three materials are reported. The capacity and conditional distribution coefficient in neutral, uranyl-contaminated synthetic groundwater containing carbonate are also reported. The suitability of each material for treating uranium-contaminated groundwater using a permeable reactive barrier (PRB) approach is then discussed. All three materials react rapidly in the pH range 5-7, reaching equilibrium in less than 4 h at ~23◦C. The unconditioned cation exchange resin removed 8 g UO22+ per kg of resin from neutral synthetic groundwater containing 30 mg/l of UO22+, but a lower capacity is anticipated in groundwater with either higher ionic strength or lower UO22+ ...
LITERATURE REVIEW: The desire to measure low metal concentrations in natural waters stems principally from the aim to understand the effects of trace metals on aquatic biota and to understand the fate of metal pollutants. Trace metals rarely exist in the free ion form, with distribution of the different species being dependent upon pH, Eh, and the types of organic/inorganic ligands and colloidal surfaces. Use of cation exchange resins, particularly Chelex-100, has been developed over the past few decades and enables preconcentration to yield, upon elution, measurable concentrations of trace metals. These resins can also yield data on the speciation (by measuring lability) of a metal in solution by adjusting the contact time of the sample with the resin. Several speciation schemes have been developed where separation techniques (such as dialysis) are coupled with Chelex-column methods (short contact time) and Chelex-batch methods (long contact time). With the exception of recent equilibrium based ...

TY - JOUR. T1 - Pathophysiology of potassium absorption and secretion by the human intestine. AU - Agarwal, Rajiv. AU - Afzalpurkar, Rekha. AU - Fordtran, John S.. PY - 1994/8. Y1 - 1994/8. N2 - When normal people ingest 90 mEq/day of K+ in their diet, they absorb about 90% of intake (81 mEq) and excrete an equivalent amount of K+ in the urine. Normal fecal K+ excretion averages about 9 mEq/day. The vast majority of intestinal K+ absorption occurs in the small intestine; the contribution of the normal colon to net K+ absorption and secretion is trivial. K+ is absorbed or secreted mainly by passive mechanisms; the rectum and perhaps the sigmoid colon have the capacity to actively secrete K+, but the quantitative and physiological significance of this active secretion is uncertain. Hyperaldosteronism increases fecal K+ excretion by about 3 mEq/day in people with otherwise normal intestinal tracts. Cation exchange resin by mouth can increase fecal K+ excretion to 40 mEq/day. The absorptive ...

Sodium polystyrene sulfonate is a non-absorbed, cation exchange polymer that contains a sodium counterion.. Sodium polystyrene sulfonate increases fecal potassium excretion through binding of potassium in the lumen of the gastrointestinal tract. Binding of potassium reduces the concentration of free potassium in the gastrointestinal lumen, resulting in a reduction of serum potassium levels. The practical exchange ratio is 1 mEq K per 1 gram of resin.. As the resin passes along the intestine or is retained in the colon after administration by enema, the sodium ions are partially released and are replaced by potassium ions. This action occurs primarily in the large intestine, which excretes potassium ions to a greater degree than does the small intestine. The efficiency of this process is limited and unpredictably variable.. ...

Norfloxacin is a common fluoroquinolones antibacterial drug having the bitter taste which hindered its oral administration. Drug resin complex mask the bitter taste of the drug and hence an attempt has been made in the present study to prepare bitterless Norfloxacin suspension using Ion exchange resins. Norfloxacin was treated with the weak cation exchange resins which form the drug resin complex called resinate. The loading process was optimized for the pH of loading solution and the drug resin ratio. The resinates were evaluated for bulk density, angle of repose, taste masking, and in vitro drug release. Taste evaluation of the drug resinates showed complete masking of the bitterness of the drug. In vitro drug release studies revealed that more than 90% of the drug was released within 20 min from the drug resinates. Sweet palatable aqueous suspension of norfloxacin was formulated successfully with drug-resin complex and it was found to be stable.
The recent introduction into clinical medicine of a group of substances known as ion exchange resins has provided the physician with a new type of diagnostic and therapeutic tool.

Natural tannins have a high affinity to absorb metal ions, proteins and some other biomolecules. In this study, tannins extracted from Terminalia arjuna (Kumbuk) were used to synthesise renewable tannin-phenol-formaldehyde resin systems and a porous modified resin system. A series of resin systems was synthesised by varying the incorporated phenol content. The ion exchange capacities of the resins produced were studied and the resin with the highest ion exchange capacity was selected. It was sulfonated to increase the properties further. A monovalent cation, Na+ was used to estimate the adsorption properties of both sulfonated and unsulfonated resin systems. Solubility and swelling properties of the resins were measured to check their applicability as an ion exchanger in aqueous media at different pH values. Fourier transform infrared spectroscopy (FTIR) analysis was carried out to characterise the synthesised resins. Scanning electronic microscopic (SEM) images were obtained to study the ...

In the present work, a new purification method of anthocyanins with o-dihydroxy arrangement is proposed. This method is based on a ligand-exchange mechanism, using a cationic exchange resin loaded with metallic ions in order to increase the affinity of the resin to the anthocyanin(s) with o-dihydroxy arrangement. This method was used to purify the main anthocyanin (cyanidin-3-glucoside; Cy-3-glc) from the anthocyanic methanolic extract of blue corn. The best sorption result was using Fe(III) in its ion form. The purification procedure begins with the formation of a metal-anthocyanin complex (Cy-3-glc-Fe) which was optimal at pH 5, followed by a NaOH 0.1?M elution process in order to eliminate anthocyanins without o-dihydroxy arrangement, sugars, and organic acids. Finally, the pure anthocyanin is obtained by adding HCl 0.1?M which breaks the metal-anthocyanin complex. ...

Palatability and physical properties of potassium-binding resin RDX7675: comparison with sodium polystyrene sulfonate Vanessa Zann,1 John McDermott,1 Jeffrey W Jacobs,2 James P Davidson,2 Fangling Lin,2 Paul Korner,2 Robert C Blanks,2 David P Rosenbaum2 1Quotient Clinical, Nottingham, UK; 2Ardelyx Inc., Fremont, CA, USA Background: Hyperkalemia is a potentially life-threatening condition that patients with heart failure or chronic kidney disease, especially those taking renin–angiotensin–aldosterone system inhibitors, are at high risk of developing. Sodium polystyrene sulfonate (SPS), a current treatment, binds potassium within the gastrointestinal tract to reduce potassium absorption. However, poor palatability limits its long-term use. RDX7675, a novel potassium binder in development for the treatment of hyperkalemia, is a calcium salt of a reengineered polystyrene sulfonate-based resin designed to have enhanced palatability. Here, the physical properties and palatability of RDX7675 and

Polystyrene sulfonates are polymers derived from polystyrene by the addition of sulfonate functional groups. They are widely used as ion-exchange resins to remove ions such as potassium, calcium, and sodium from solutions in technical or medical applications. Linear ionic polymers are generally water-soluble, whereas cross-linked materials (called resins) do not dissolve in water. These polymers are classified as polysalts and ionomers. Polystyrene sulfonate is usually supplied in either the sodium or calcium form. It is used as a potassium binder in acute and chronic kidney disease for people with hyperkalemia (abnormal high blood serum potassium levels). However, it is unclear if it is medically beneficial and there is concern about possible side effects when it is combined with sorbitol. Polystyrene sulfonates are given by mouth with a meal or rectally by retention enema. Under the name tolevamer, a polystyrene sulfonate was investigated by Genzyme as a toxin binding agent for the treatment ...
The relative activities of four disiloxanes toward the cation exchange resin, which was used as an equilibration catalyst, were determined in such a way that the equilibrium initialy present in an arbitrary chosen equilibrate was disturbed by adding the respective disiloxanes to it, and then by recording the viscosity of the equilibrating mixtures as a function of reaction time.As a result, a set of different viscosity-reaction time relationships was obtained, which implies different activities of disiloxanes toward the catalyst. In this way the following decreasing order of activities was established : 1,3-tetramethyldisiloxane,1,3-divinyltetramethyldisiloxane ,hexamethyldisiloxane ,1,3-bis( 3-carboxypropyl)tetramethyldisiloxane ...
