A series consisting of 117 2-(halogenated phenyl) acetamide and propanamide analogs were investigated as TRPV1 antagonists. The structure–activity analysis targeting their three pharmacophoric regions indicated that halogenated phenyl A-region analogs exhibited a broad functional profile ranging from agonism to antagonism. Among the compounds, antagonists 28 and 92 exhibited potent antagonism toward capsaicin for hTRPV1 with Ki[CAP] = 2.6 and 6.9 nM, respectively. Further, antagonist 92 displayed promising analgesic activity in vivo in both phases of the formalin mouse pain model. A molecular modeling study of 92 indicated that the two fluoro groups in the A-region made hydrophobic interactions with the receptor.

The new series of 2-(substituted-phenyl)acetohydrazides analogs, S-alkylated 5-substituted-1,3,4-oxadiazoles-2-thione derivatives and 5-arylidene-3-substituted-1,2,4-triazines have been synthesized in good yields and characterized by IR, NMR, mass spectral and elemental analyses. All the synthesized compounds 4(a-d), 5(a-d), 7(a-b), and 8(a-f) are evaluated for their in vitro DPPH scavenging, antimicrobial activity, in vivo analgesic, anti-inflammatory activities. The results of the anti-inflammatory activity are supported by molecular docking study with mouse COX-1 (PDB ID: 2CZT) and COX-2 (PDB ID: 3LN1) enzymes to predict their putative interactions. Among all the assays conducted, the compounds 5-(4-bromophenyl)-3-(naphthalen-2-ylmethyl)-1,2,4-triazine (4d) and2-{[5-(diphenylmethyl)-1,3,4-oxadiazol-2-yl]sulfanyl}-N-(pyrazin-2-yl)acetamide (8a) have emerged as the most potent molecules.

Transition-metal-free synthesis of α-aryl esters and nitriles using arylboronic acids with α-aminoesters and α-aminoacetonitriles, respectively, as the starting materials has been developed. The reaction represents a rare case of converting C(sp3)-N bonds into C(sp3)-C(sp2) bonds. The reaction conditions are mild, demonstrate good functional-group tolerance, and can be scaled up. Touch base: A transition-metal-free protocol for the synthesis of α-aryl esters and nitriles by deaminative coupling is presented. Strong bases and transition-metal catalysts are not needed. The new synthetic method uses readily available starting materials and demonstrates wide substrate scope.
