4-[1-(Substituted aryl/alkyl carbonyl)-benzoimidazol-2-yl]-benzenesulfonic acids: Synthesis, antimicrobial activity, QSAR studies, and antiviral evaluation

“…The appearance of C]O stretch in the range of 1630e1600 cm À1 indicated the formation of tertiary amides (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20) by the reaction of acid chlorides with the 4-(1H-benzoimidazol-2yl)-benzenesulfonic acid. The primary amino group in compound 1 is depicted by the presence of NH asymmetric stretch at 3481.81 cm À1 .…”

“…Furthermore, the topological parameter, Balaban index (J) followed by the electronic parameter, LUMO and topological parameter, valence second order molecular connectivity index ( 2 c v ) is describing the antimicrobial activity of 4-[1-(substituted aryl/alkyl carbonyl)-benzoimidazol-2-yl]-benzenesulfonic acids (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20).…”

Efficient one pot preparation of novel 1-oxo-3-aryl-1,5-dihydrobenzo[4,5]imidazo[1,2-a]pyridine-2-carboxylic acid derivatives in a green solvent

“…3 These compounds are the core of many strategic and widely used drugs that have received excellent feedback in the medical and the chemical field as efflux pumps Inhibitors A, 4 GABA-A receptors (RWJ-16979) B, 5 adrenoreceptors C, 6 RWJ-51204 D, 7 and fluorescence microscopy E. 8 Also, these compounds have biological properties such as anxiolytic agents, 5 anticonvulsive, 9 antimicrobial, 10 relaxant agents, 5 as cell proliferation inhibitors or quadruplex nucleotide stabilizers in DNA, 11 anticancer, 12 antimalarial agents, 13 and human estrogenic receptor activators (Figure 1). 14 Because the benzo [4,5]imidazo [1,2-a]pyridine scaffold show interesting biological activities, the synthesis of this group of compounds has been realised via several routes, including cycloaddition reactions, 6,9,15 condensation reactions, [16][17][18] multicomponent reactions, 10,[19][20][21][22][23] and multistep approaches. 5,[24][25][26] Also, metallic and non-metallic catalysts, [27][28][29][30] microwave irradiation, 31 and a series of transition metal catalysts have been used for the preparation of these compounds.…”
