Nine-membered enediyne antitumor antibiotics C-1027, neocarzinostatin (NCS), and kedarcidin (KED) possess enediyne cores to which activity-modulating peripheral moieties are attached via (R)- or (S)-vicinal diols. We have previously shown that this stereochemical difference arises from hydrolysis of epoxide precursors by epoxide hydrolases (EHs) with different regioselectivities. The inverting EHs, such as SgcF, hydrolyze an (S)-epoxide substrate to yield an (R)-diol in C-1027 biosynthesis, whereas the retaining EHs, such as NcsF2 and KedF, hydrolyze an (S)-epoxide substrate to yield an (S)-diol in NCS and KED biosynthesis. We now report the characterization of a series of EH mutants and provide a predictive model for EH regioselectivity in the biosynthesis of the nine-membered enediyne antitumor antibiotics. A W236Y mutation in SgcF increased the retaining activity toward (S)-styrene oxide by 3-fold, and a W236Y/Q237M double mutation in SgcF, mimicking NcsF2 and KedF, resulted in a 20-fold ...
Enediyne antibiotics have been reported to be the most potent cytotoxic antitumor agents. The pathway by which these compounds cleave DNA and induce apoptosis of tumor cells may be different from the caspase-mediated pathways that initiate typical apoptosis. In this report, we studied the apoptosis induced by lidamycin (LDM), a member of the enediyne antibiotic family, and compared the characteristics of LDM-induced apoptosis with those of typical apoptosis induced by mitomycin C or etoposide. Chromatin condensation occurred very rapidly and appeared as speckles in human hepatoma BEL-7402 and breast carcinoma MCF-7 cells after treatment with I muM LDM. In addition, co-staining the cells with the mitochondria-specific dye Mitosensor(TM) and the DNA-specific dye Hoechst 33342 enabled the visualization of mitochondria in normal control and LDM-treated cells but not in mitomycin C-treated cells. Neither the caspase inhibitor VAD-fmk nor the caspase-3 inhibitor DEVD-fmk was able to inhibit the DNA ...
The thermal cyclisation of enediynes to benzene-1,4-diyl diradicals (Bergman cyclisation) is affected by geometrical and electronic conditions. While the effect of ring strain or conformational constrains on the cyclisation temperature has been investigated in detail, electronic contributions have been less studied. Often geometrical and electronic contributions cannot be clearly distinguished. In most cases metal ion chelation does involve both. In this review we have summarised clear-cut observations of electronic substituents effects on the thermal enediyne reactivity. The effects of substituents in the vinylic and terminal alkyne position, the influence of benzo-fusion and hetarene fusion, as well as the changes induced by heteroatoms in the enediyne skeleton, are within the scope of this review. With the exception of more complex heterocyclic hetarene-fused enediynes the experimental data of electronic substituent effects on the thermal Bergman cyclisation of enediynes follow theoretical ...
Pascal begins with the assumption that terminal aryl substitution on the enediyne will both (a) inhibit the C1-C6 cyclization due to steric interactions and (b) the C1-C5 cyclization should be enhanced due to stabilization of the radical by the neighboring aryl group. He computed the activation energies of a series of analogues, some of which are listed in Table 1. The transition state structures are shown in Figure 1 for 1b and 1c. Phenyl substitution does accomplish both suggestions: the activation barrier for the Bergman cyclization increases by 4 kcal mol-1, while the barrier for the C1-C5 cyclization is lowered by nearly 6 kcal mol-1. Further substitution of the phenyl ring by either chloro or methyl groups brings the barriers into near degeneracy.. Table 1. RBLYP/6-31G(d) Activation energies (kcal mol-1) ...

The gene lndI is involved in the pathway-specific positive regulation of biosynthesis of the antitumour polyketide landomycin E in Streptomyces globisporus 1912. LndI was overexpressed in Escherichia coli as a protein C-terminally fused to the intein-chitin-binding-domain tag and purified in a one-step column procedure. Results of in vivo LndI titration, DNA gel mobility-shift assays and promoter-probing experiments indicate that LndI is an autoregulatory DNA-binding protein that binds to its own gene promoter and to the promoter of the structural gene lndE. Enhanced green fluorescent protein was used as a reporter to study the temporal and spatial pattern of lndI transcription. Expression of lndI started before cells entered mid-exponential phase and peak expression coincided with maximal accumulation of landomycin E and biomass. In solid-phase analysis, lndI expression was evident in substrate mycelia but was absent from aerial hyphae and spores.
Gemtuzumab Ozogamicin (CMA-676) is a chemotherapeutic agent consisting of a recombinant humanized anti-CD33 antibody conjugated with calicheamicin, a highly potent cytotoxic antitumor antibiotic. The antibody portion of Gemtuzumab binds specifically to the CD33 antigen, a sialic acid-dependent adhesion protein expressed on the surface of leukemic blasts, normal and leukemic myeloid colony-forming cells, including leukemic clonogenic precursors, but excluding pluripotent hematopoietic stem cells and nonhematopoietic cells. This results in formation of a complex that is internalized, upon which the calicheamicin derivative is released within the lysosomes of the myeloid cell. The free calicheamicin derivative then binds to deoxyribonucleic acid (DNA), resulting in DNA double strand breaks and consequential cell death. Over 80% of AML patients possess myeloid blast cells with CD33 surface antigen expression ...

Neurotrophins have been implicated in positive and negative modulation of the susceptibility of neural tumors to chemotherapeutic agents (Cortazzo et al., 1996; Kim et al., 1999;Schor, 1999). NGF, the first neurotrophin described, has been found to variably induce or prevent apoptosis of normal and neoplastic neural cells, depending upon the method by which apoptosis is induced and which of the two known NGF receptors (p75 or TrkA) is involved in mediating the response to NGF (Bredesen and Rabizadeh, 1997; Bredesen et al., 1998).. In addition, previous studies have demonstrated the multiple roles of the p75 receptor (Frade and Barde, 1998) and have suggested that its predominant role varies from cell type to cell type (Cortazzo et al., 1996). What determines the function of p75 in different cell types or in the same cell at different times in its development remaines unclear (Fundin et al., 1997). Several studies have indicated that p75 binding to TrkA, TrkB, or TrkC enhances the affinity of the ...
The EMA acknowledges that mandating sponsors to conduct post-marketing studies and carrying out their long-term monitoring plan would provide necessary safeguard of patient safety. However, the devil is in the detail: since the conclusion of AP pilot, the EMA has conceded that identifying methodologically sound strategies of real-world evidence collection to support the agencys initial assessment of efficacy and effectiveness remains challenging.[25] Critics of AP schemes further point out that post-marketing surveillance based on observational evidence tend to overestimate the clinical benefits as compared to randomised controlled trials.[26] Nonetheless, for Holoclar, the sponsor is required to submit a five-year follow-up with the final report due on June 2023, and interim reports to be provided annually during the observation period.[27] According to the EMA, the sponsor of Holoclar is required to provide multinational, multicentre, prospective, open-label, uncontrolled interventional ...
Good but hard day today. I talked with the neurologist this morning. I found out today that all the moving hes doing with his arms and legs, which they call "restlessness" is usually seen in Rancho level 4. She explained to me that the Rancho scale is cognitive, so 1 is deep coma like right after the accident. Cale is at the baseline of 3 right now. The more severe the brain injury, the sooner they see this. Cale was showing it in level 2. I already knew that his brain injury was severe and that he was in bad shape, but since I was seeing movement so soon, I was thinking that he was making such quick progress. I felt like he was getting better so quick and that in the back of my head the long road was going to be a lot shorter for us. Also, at the end of the conversation I asked how well she thought Cale was doing and she said that over the last 6 weeks his progress has been very slow and thats about how things are going to go. She said with how bad the injury was its going to take a lot off ...

In the article by I. Georis, A. Feller, J. Tate, T. Cooper and E. Dubois (Genetics 181: 861-874) entitled "Nitrogen Catabolite Repression-Sensitive Transcription as a Readout of Tor Pathway Regulation: The Genetic Background, Reporter Gene and GATA Factor Assayed Determine the Outcomes," strain 25T0b and all strains constructed from it (Table 1 in that article), labeled as isogenic to Sigma, are actually isogenic to S288C. The parent strain, 25T0b, emanated from the sporulation of a diploid strain isogenic to S288C [FY23 × FY73; F. Winston, C. Dollard and S. L. Ricupero-Hovasse (Yeast 11: 53-55)]. Therefore, those portions of the article addressing the resolution of the paradoxical observations obtained in TB123 vs. Sigma genetic backgrounds or mutant phenotypes reported for the Sigma genetic background are no longer valid because no Sigma strains were used in the experiments. Those data instead provide descriptions of mutant phenotypes and events occurring in the S288C genetic background. ...
Punk was revolting against everything. But the first American wave was more tied to literary antecedents than political ones; the latter was more the UK remit, which I think is where the whole notion of rebellion came into play. My own experience of first-wave punk was that it was more nihilist and truly anarchic than anything else -- there was no agenda, just a general desire for cultural defenestration. The soundtrack that best captured that feeling at the time (and still does now) is Patti Smiths live cover of My Generation, during which she starts babbling nonsense before the whole thing descends into chaos and ends with Patti famously stating We created it, lets take it over. I used to play that 45 over and over again on the jukebox at Deer Park, the Katonah dive where I left a lot of my brain cells. I actually heard her do that song in 1975 with John Cale, though not the performance that was later recorded ...

So, Renminbi has changed their name to Magnetic Island. The band plans to release songs more frequently (basically right after they are mastered) instead of waiting until they have the traditional 10-12 tracks for an album. This is their first release under their new moniker, a cover of a Lou Reed and John Cale track from the Songs For Drella concept album. Listen…. Downloadable: A Dream (mp3). If you followed @renminbinyc, hearing this song should explain those #SongsForDrellaFactoids that were showing up recently. Theres much more info on the track @ the Magnetic Island CASH music page.

První píseň na albu, bezmála tříminutová „Hello There", svou atmosférou připomíná styl skupiny The Band, avšak Cale k ní napsal text s prvky britského humoru. Následuje „Gideons Bible" (původním názvem „A Day with Clancy"), jejíž valivý rytmus je doprovázen výraznou kytarou a abstraktním textem. Následuje „Adelaide" a po ní „Big White Cloud", ve které Cale diriguje smyčcovou sekci. Americký hudebník Anthony LaMarca nahrál vlastní verzi písně „Big White Cloud" a zařadil ji mezi „písně, které by si přál napsat".[12] Píseň „Cleo" provází výrazné varhany a ženské vokály.[4] Na šesté pozici se nachází countryrocková čtyřminutová píseň „Please".[3] Na první pozici druhé strany původní vinylové desky se nachází pětiminutová „Charlemagne" začínající hrou na klavír. Následují „Bring It on Up" a tichá akustická píseň „Amsterdam". V úvodu písně „Ghost Story" jsou opět slyšet varhany a její text ...

nisse at lysator.liu.se (Niels Möller) writes: I guess its lowest numbered first (and lowest memory address). But a loop with use r7 ldm up!, {r4,r5,r6,r7} use r4 looks like poor scheduling betwen load of r4 and use of it, and the ldm cant be moved earlier since it clobbers r7. But I have a pretty vague idea about how this really works. I havent explored the ARM chips enough to know thi either. A possible schedule is to put a stm in the ldm latency time slot: ldm {r4-r7} stm {r8-r11} ldm {r8-r11} operate on r4-r7 operate on r4-r11 The operate on blocks dont need to be as disjoint as the picture seems to suggest. Right, rewriting the loop with 3-way unrolling would be an interesting experiment. But I dont think Ill look into that soon. The current improvement is very good already. Its hard to organise the ARM code. Since we have a very incomplete set of systems, we might choose a poor asm file vector for some systems. If you new code runs well on A15, perhaps we should assume it is good ...

Cale performs the Falkland Island Suite in Holland and we get to see the bored reaction of some Dutch music critics. They tell us that Cale is over the hill. Thus encouraged, we follow Cale to Moscow where he and Eno will make a studio recording for the orchestral part to Falkland. Along the way we meet a character named Rodin, a Russian musician affected by somatomegaly or some other form of gigantism and who plays the double bass. The guys hands are so big it looks more like hes playing a cello. It was difficult for me to tell if he was once a good player that has slipped or he is just so unique that hes off in a zone by himself. Nevertheless, both Cale and Eno are impressed enough to write a chart just for him and then they spend considerable time trying to get something out of Rodin they can use on the album. Then its on to Wales where we get off-task again while Cale helps his aged mother sell the family home. Eventually we come around to Cale working with the Llandaff Cathedral School ...

CIRT is a randomized trial, which means that participants are put into one of two study groups by a coin-toss type procedure, known as randomization. Half the participants will receive an active study drug, low dose methotrexate (LDM) and half will receive an inactive study drug, known as "placebo." The study medication, LDM, is a widely used anti-inflammatory treatment for rheumatoid arthritis and it has a well documented safety profile.. Initially, all participants enter a "run-in" phase, when they take the study drug LDM for a period of about six weeks.. During this time patients are watched closely for any problems tolerating LDM. After the run-in period, there is the coin toss, randomization procedure, in which neither the patient nor the research study team knows whether the patient is on LDM or placebo (this is what is meant by double blinded) for the rest of the study period.. Eligible participants are followed up to 5 years. During that period, participants will receive all of their ...
