Synthesis and characterization of orally active nonpeptide vasopressin V2 receptor antagonists

The present study was undertaken to evaluate whether a novel series of 2,6-diaza-5-oxobicyclo[5.4.0]undeca-1(7),8,10-triene derivatives exhibited antagonistic activity for vasopressin V1 and V2 receptors. Most of these compounds were synthesized and showed a high affinity potential for V2 receptor and low to moderate affinity potential for V1 receptor. The most potent and V2-selective compound, N-[4-[2,6-diaza-6-[2-(4- methylpiperazinyl)-2-oxoethyl]-5-oxobicyclo [5.4.0] undeca-1 (7),8,10-trien- 2-yl]-carbonyl]phenyl] [2-(4-methylphenyl)phenyl]formamide (11b), exhibited IC50’s of 2.9 nM for the V2 receptor and 200 nM for the V1 receptor, respectively. When administered orally to rat, 11b showed an approximately 18-fold increased urine volume in comparison with control rat.

Design, synthesis, molecular modeling and anti-hyperglycemic evaluation of novel quinoxaline derivatives as potential PPARgamma and SUR agonists

In our effort to develop potent anti-hyperglycemic agents with potential agonistic activities toward PPARgamma and SUR, three novel series of quinoxaline derivatives bearing sulfonylurea or sulfonylthiourea moieties with different linkers were designed and synthesized. Some of the newly synthesized compounds were evaluated in vivo for their anti-hyperglycemic activities in STZ-induced hyperglycemic rats. Compounds 15a, 15e, 19band 24aexhibited the highest anti-hyperglycemic activities with % reduction in blood glucose level of (50.58, 43.84, 45.10 and 49.62, respectively). Additionally, eight compounds revealed potent anti-hyperglycemic activities were further evaluated in vitro for their PPARgamma binding affinity and insulin-secreting ability as potential mechanisms for anti-hyperglycemic activity. Four compounds (15a, 15b, 15dand 15e) significantly bound to PPARgamma with IC50values of 0.482, 0.491, 0.350 and 0.369 muM, respectively. Moreover, Compounds 15aand 15bhave demonstrated induction of insulin-secretion with EC50values of 0.92 and 0.98 muM, respectively. Furthermore, molecular docking and pharmacophore generation techniques were carried out to investigate binding patterns and fit values of the designed compounds with PPARgamma and SUR, respectively.

HDAC as onco target: Reviewing the synthetic approaches with SAR study of their inhibitors

Even though one is moving towards the success in the discovery of efficient anti-cancer molecules, the drugs used in the treatment of various malignancies are found to possess toxicity and adverse reactivity in the human body that limit their use. The scientists all over the world are engaged in bringing up strategies that aim to develop small molecules that target the abnormal epigenetic factors. The discovery of the role of Histone deacetylases (HDACs) has promised to be a turning point in the treatment of various malignancies. Thus, the invention of potent and safe anticancer therapeutics agents with minimal adverse and side effects are still a major topic of concern and a huge number of research works have been reported in the past few years. This review has been written to discuss on the influence of Histone Deacetylases in cancer malignancies. We have tried to embrace majority of the developments made till date in the field of HDAC and its inhibitors herein. The drugs that are clinically applied, synthesis and SAR study that highlight the chemical groups responsible for evoking the HDAC inhibition and potential of various new classes of HDAC inhibitors (synthetic, hybrid and natural) have also been included.

Discovery of a new chemical series of BRD4(1) inhibitors using protein-ligand docking and structure-guided design

Bromodomains are key transcriptional regulators that are thought to be druggable epigenetic targets for cancer, inflammation, diabetes and cardiovascular therapeutics. Of particular importance is the first of two bromodomains in bromodomain containing 4 protein (BRD4(1)). Protein-ligand docking in BRD4(1) was used to purchase a small, focused screening set of compounds possessing a large variety of core structures. Within this set, a small number of weak hits each contained a dihydroquinoxalinone ring system. We purchased other analogs with this ring system and further validated the new hit series and obtained improvement in binding inhibition. Limited exploration by new analog synthesis showed that the binding inhibition in a FRET assay could be improved to the low muM level making this new core a potential hit-to-lead series. Additionally, the predicted geometries of the initial hit and an improved analog were confirmed by X-ray co-crystallography with BRD4(1).

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Application In Synthesis of 3,4-Dihydroquinoxalin-2(1H)-one, you can also check out more blogs about59564-59-9

Conformationally constrained ortho- Anilino diaryl ureas: Discovery of 1-(2-(1?-Neopentylspiro[indoline-3,4?-piperidine]-1-yl)phenyl) -3-(4-(trifluoromethoxy)phenyl)urea, a potent, selective, and bioavailable P2Y1 antagonist

Preclinical antithrombotic efficacy and bleeding models have demonstrated that P2Y1 antagonists are efficacious as antiplatelet agents and may offer a safety advantage over P2Y12 antagonists in terms of reduced bleeding liabilities. In this article, we describe the structural modification of the tert-butyl phenoxy portion of lead compound 1 and the subsequent discovery of a novel series of conformationally constrained ortho-anilino diaryl ureas. In particular, spiropiperidine indoline-substituted diaryl ureas are described as potent, orally bioavailable small-molecule P2Y1 antagonists with improved activity in functional assays and improved oral bioavailability in rats. Homology modeling and rat PK/PD studies on benchmark compound 3l will also be presented. Compound 3l was our first P2Y1 antagonist to demonstrate a robust oral antithrombotic effect with mild bleeding liability in the rat thrombosis and hemostasis models.

Unnatural alpha-Amino Acid Synthesized through alpha-Alkylation of Glycine Derivatives by Diacyl Peroxides

We have developed a protocol for catalyst- and additive-free alpha-alkylation reactions of glycine derivatives with diacyl peroxides, which proceed by a pathway involving addition of alkyl radicals to imine intermediates. The diacyl peroxide substrate acts as both alkylation agent and oxidizing agent, which means it is atom-economical. It was applied to various glycine derivatives, dipeptides, and a 3,4-dihydroquinoxalin-2(1H)-one derivative and could be carried out on a gram scale, indicating its utility for late-stage functionalization.

Steering the antitumor drug discovery campaign towards structurally diverse indolines

Indoline framework is often perpended as a privileged heterocycle present in medicinally valuable compounds of natural and synthetic origin. This review article presents the rational approaches/strategies employed for the design of anticancer indolines along with the structure activity relationship and mechanistic insights revealed in the in-vitro and in-vivo assays. The chemist has always been fascinated towards the indoline ring for the construction of antitumor scaffolds owing to its versatility as evidenced by its existence in scaffolds inducing antiproliferative effects via diverse mechanisms. To the delight of medicinal chemist, the applicability of indoline has also been expanded towards the design of dual inhibitors (multitargeting anticancer agents) as well as PROTACS. Overall, it can be concluded that indoline moiety is a magic bullet and the scaffolds containing this ring are foraying towards detailed preclinical and clinical stage investigations by leaps and bounds.
