Two independent approaches resulted in the identification of a series of isoindolone derivatives, e.g., I, as potent and selective 5-HT2C antagonists. From a Medicinal Chem. perspective this template was considered interesting as it allowed the incorporation of the carbon-carbon double bond of an earlier dihydropyrrolone series in an aromatic system within a comparatively simple and compact motif. Addnl. an in silico screening approach of the corporate database using a 5-HT2C pharmacophore model resulted in the identification of a related structure containing this template. The strategy used to optimize potency at the target receptor and to improve the pharmacokinetic profile is described, resulting in mols. combining high potency with good selectivity and oral bioavailability.

Cho, Sung Jin published the artcileSelective 5-Hydroxytryptamine 2C Receptor Agonists Derived from the Lead Compound Tranylcypromine: Identification of Drugs with Antidepressant-Like Action, Formula: C8H6ClFO, the main research area is serotonin receptor 5HT2c agonist antidepressant tranylcypromine derivative SAR preparation.

We report here the design, synthesis, and pharmacol. properties of a series of compounds related to tranylcypromine (9), which itself was discovered as a lead compound in a high-throughput screening campaign. Starting from 9, which shows modest activity as a 5-HT2C agonist, a series of 1-aminomethyl-2-phenylcyclopropanes was investigated as 5-HT2C agonists through iterative structural modifications. Key pharmacophore feature of this new class of ligands is a 2-aminomethyl-trans-cyclopropyl side chain attached to a substituted benzene ring. Among the tested compounds, several were potent and efficacious 5-HT2C receptor agonists with selectivity over both 5-HT2A and 5-HT2B receptors in functional assays. The most promising compound is 37, with 120- and 14-fold selectivity over 5-HT2A and 5-HT2B, resp. (EC50 = 585, 65, and 4.8 nM at the 2A, 2B, and 2C subtypes, resp.). In animal studies, compound 37 (10-60 mg/kg) decreased immobility time in the mouse forced swim test.

Asadollahi-Baboli, M. published the artcileStraightforward MIA-QSTR evaluation of environmental toxicities of aromatic aldehydes to Tetrahymena pyriformis, Recommanded Product: 6-Chloro-2-fluoro-3-methylbenzaldehyde, the main research area is quant structure activity relationship aromatic aldehyde Tetrahymena ecotoxicity.

Aldehydes are toxic environmental contaminants which cause severe health hazards. There is a growing need by industries and regulatory agencies for the development of tools able to assess the potential hazardous effects of chems. on living organisms. In this background, multivariate image anal. combined with quant. structure-toxicity relationships (MIA-QSTR) was used to evaluate the toxicity of aromatic aldehydes to Tetrahymena pyriformis. The techniques of genetic algorithm-partial least squares (GA-PLS) were applied effectively as MIA descriptor selection and mapping tools. In MIA-QSTR evaluation, pixels of 2D images of chem. structures could be used to recognize physicochem. information and predict changes in the toxicities. The resulting MIA-QSTR explains 90.3% leave-one-out predicted variance and 93.1% external predicted variance. The MIA-QSTR/GA-PLS performances were validated using various evaluation techniques such as cross-validation, applicability domain and Y-scrambling procedures, suggesting that the present methodol. together with mechanistic interpretation may be useful to evaluate toxicity, safety and risk assessment of toxic environmental contaminants.

The P2Y14 nucleotide receptor, a subtype of P2Y receptors, is implicated in many human inflammatory diseases. Based on the identification of favorable residues of two screening hits in the almost sym. P2Y14 binding domain, we describe the structural optimization of previously identified virtual screening hits 6 and 7 that result in the development of P2Y14R antagonists with a novel 2-phenyl-benzoxazole acetamide chem. scaffold. Notably, compound 52 showed potent P2Y14R antagonistic activity (IC50 = 2 nM), and a stronger inhibitory effect on MSU-induced inflammatory in vitro, better than a previously described P2Y14R antagonist PPTN. In vivo evaluation demonstrated that compound 52 also had satisfactory inhibitory activity on the inflammatory response of gout flares in mice. Moreover, P2Y14R antagonist 52 decreased paw swelling and inflammatory cell infiltration through cAMP/NLRP3/GSDMD signaling pathways in MSU-induced acute gouty arthritis mice. The discussions on the binding mechanism that employ MM/GBSA free energy calculations/decompositions also provide some useful clues for further structural designing of compound 52. Taken together, 2-phenyl-benzoxazole acetamide derivative 52 with potent P2Y14R antagonistic activity and in vivo potency could be a promising strategy for gout therapy and deserves further optimization.

We report here a scalable, catalytic one-pot approach to enantiopure and unmodified β²-amino acids. A newly developed confined imidodiphosphorimidate (IDPi) catalyzes a broadly applicable reaction of diverse bis-silyl ketene acetals with a silylated aminomethyl ether, followed by hydrolytic workup, to give free β²-amino acids in high yields, purity, and enantioselectivity.

Mechanistic studies are consistent with the aminomethylation to proceed via silylium-based asym. counteranion-directed catalysis (Si-ACDC) and a transition state to explain the enantioselectivity is suggested on the basis of d. functional theory calculation
