On January 12, 2017, Bremer, Paul T.; Adler, Michael; Phung, Cecilia H.; Singh, Ajay K.; Janda, Kim D. published an article.Application In Synthesis of 6-Chloro-2,3-dihydro-1H-indole The title of the article was Newly Designed Quinolinol Inhibitors Mitigate the Effects of Botulinum Neurotoxin A in Enzymatic, Cell-Based, and ex Vivo Assays. And the article contained the following:

Botulinum neurotoxin A (BoNT/A) is one of the most deadly toxins, and is the etiol. agent of the potentially fatal condition, botulism. Herein, the authors investigated 8-hydroxyquinoline (quinolin-8-ol) as a potential inhibitor scaffold for preventing the deadly neurochem. effects of the toxin. Quinolinols are known chelators that can disrupt the BoNT/A metalloprotease zinc-containing active site, thus impeding its proteolysis of the endogenous protein substrate, synaptosomal-associated protein 25 (SNAP-25). Using this information, the structure-activity relationship (SAR) of the quinolinol-5-sulfonamide scaffold was explored through preparation of a crude sulfonamide library, and evaluating the library in a BoNT/A LC enzymic assay. Potency optimization of the sulfonamide hit compounds was undertaken as informed by docking studies, granting a lead compound with a submicromolar Ki. These quinolinol analogs demonstrated inhibitory activity in a cell-based model for SNAP-25 cleavage and an ex vivo assay for BoNT/A-mediated muscle paralysis. The experimental process involved the reaction of 6-Chloro-2,3-dihydro-1H-indole(cas: 52537-00-5).Application In Synthesis of 6-Chloro-2,3-dihydro-1H-indole

J.; Rong, Lijun published an article.Formula: C8H8ClN The title of the article was Discovery and Structural Optimization of 4-(Aminomethyl)benzamides as Potent Entry Inhibitors of Ebola and Marburg Virus Infections. And the article contained the following:

The recent Ebola epidemics in West Africa underscore the great need for effective and practical therapies for future Ebola virus outbreaks. We have discovered a new series of remarkably potent small mol. inhibitors of Ebola virus entry. These 4-(aminomethyl)benzamide-based inhibitors are also effective against Marburg virus. Synthetic routes to these compounds allowed for the preparation of a wide variety of structures, including a conformationally restrained subset of indolines (compounds 41-50). Compounds 20, 23, 32, 33, and 35 are superior inhibitors of Ebola (Mayinga) and Marburg (Angola) infectious viruses. Representative compounds (20, 32, and 35) have shown good metabolic stability in plasma and liver microsomes (rat and human), and 32 did not inhibit CYP3A4 nor CYP2C9. These 4-(aminomethyl)benzamides are suitable for further optimization as inhibitors of filovirus entry, with the potential to be developed as therapeutic agents for the treatment and control of Ebola virus infections. The experimental process involved the reaction of 6-Chloro-2,3-dihydro-1H-indole(cas: 52537-00-5).Formula: C8H8ClN

Reversible tetrapeptide-based compounds have been shown to effectively inhibit the hepatitis C virus NS3·4A protease. Inhibition of viral replicon RNA production in Huh-7 cells has also been demonstrated. We show herein that the inclusion of hydrogen bond donors on the P4 capping group of tetrapeptide-based inhibitors result in increased binding potency to the NS3·4A protease. The capping groups also impart significant effects on the pharmacokinetic profile of these inhibitors.

J.; Zhao, Lihua; Bourgeat, Pierre; Rose, Christiane; Vargas, Froylan; Schwartz, Jean-Charles published an article.Related Products of 79815-20-6 The title of the article was Inhibitors of Tripeptidyl Peptidase II. 3. Derivation of Butabindide by Successive Structure Optimizations Leading to a Potential General Approach to Designing Exopeptidase Inhibitors. And the article contained the following:

The cholecystokinin-8 (CCK-8)-inactivating peptidase is a serine peptidase that has been shown to be a membrane-bound isoform of tripeptidyl peptidase II (EC 3.4.14.10). It cleaves the neurotransmitter CCK-8 sulfate at the Met-Gly bond to give Asp-Tyr(SO3H)-Met-OH + Gly-Trp-Met-Asp-Phe-NH2. Starting from Val-Pro-NHBu, a dipeptide of submicromolar affinity that had previously been generated to serve as a lead, successive optimization at P3, P1, and then P2 gave Abu-Pro-NHBu (18, Ki = 80 nM). Further transformation (by making a benzologue) gave the indoline analog, butabindide (33) as a reversible inhibitor having nanomolar affinity (Ki = 7 nM). Retrospective anal. suggested the possibility of a general approach to designing exopeptidase inhibitors starting from the structure of the first hydrolysis product. Application of this approach to CCK-8 led to Abu-Phe-NHBu (37), but this only had Ki = 9.4 μM. Mol. modeling, to determine the min. energy conformations and explain the 1000-fold better affinity of butabindide, indicated that 37 cannot access the likely active conformation of butabindide. The experimental process involved the reaction of H-Idc-OH(cas: 79815-20-6).Related Products of 79815-20-6

And the article contained the following:

N-Acyl amino acids directly bind mitochondria and function as endogenous uncouplers of UCP1-independent respiration. The authors found that administration of N-acyl amino acids to mice improves glucose homeostasis and increases energy expenditure, indicating that this pathway might be useful for treating obesity and associated disorders. The authors report the full account of the synthesis and mitochondrial uncoupling bioactivity of lipidated N-acyl amino acids and their unnatural analogs. Unsaturated fatty acid chains of medium length and neutral amino acid head groups are required for optimal uncoupling activity on mammalian cells. A class of unnatural N-acyl amino acid analogs, characterized by isoindoline-1-carboxylate head groups, were resistant to enzymic degradation by PM20D1 and maintained uncoupling bioactivity in cells and in mice. The experimental process involved the reaction of H-Idc-OH(cas: 79815-20-6).Related Products of 79815-20-6

And the article contained the following:

Inhibitor of apoptosis proteins (IAPs) are important regulators of apoptosis and pro-survival signaling pathways whose deregulation is often associated with tumor genesis and tumor growth. IAPs have been proposed as targets for anticancer therapy, and a number of peptidomimetic IAP antagonists have entered clin. trials. Using the fragment-based screening approach, the authors identified nonpeptidic fragments binding with millimolar affinities to both cellular inhibitor of apoptosis protein 1 (cIAP1) and X-linked inhibitor of apoptosis protein (XIAP). Structure-based hit optimization together with an anal. of protein-ligand electrostatic potential complementarity allowed us to significantly increase binding affinity of the starting hits. Subsequent optimization gave a potent nonalanine IAP antagonist I structurally distinct from all IAP antagonists previously reported. The lead compound had activity in cell-based assays and in a mouse xenograft efficacy model and represents a highly promising start point for further optimization. The experimental process involved the reaction of 6-Chloro-2,3-dihydro-1H-indole(cas: 52537-00-5).Recommanded Product: 52537-00-5

A number of Et 4-[(1-substituted indol-2-yl)methoxy]benzoates and indoline derivatives were prepared as rigid congeners of Et 4-(2-benzylhexyloxy)benzoate (KF-13), an anti-juvenile hormone (anti-JH) agent, and tested for both anti-JH and JH activities in silkworm larvae. In contrast to KF-13, the precocious metamorphosis-inducing activity of which decreased by increasing the applied doses, 1-Pr, 1-Bu (1c) and 1-benzyl (1d) derivatives were found to induce higher percentages of precocious metamorphosis at high doses. Compounds 1c and 1d also exhibited JH activity when topically applied to allatectomized 4 th instar larvae. Et 4-[(S)-(1-n-butylindolin-2-yl)methoxy]benzoate, which showed precocious metamorphosis-inducing activity at high doses, had no JH activity.
