From Methaqualone and Beyond: Structure - Activity Relationship of 6-, 7-, and 8-Substituted 2,3-Diphenyl-quinazolin-4(3H)-ones and in Silico Prediction of Putative Binding Modes of Quinazolin-4(3H)-ones as Positive Allosteric Modulators of GABAA

Methaqualone (2-methyl-3-(o-tolyl)-quinazolin-4(3H)-one, MTQ) is a moderately potent positive allosteric modulator (PAM) of GABAA receptors (GABAARs). In a previous structure-activity relationship (SAR) study probing the importance of 2- and 3-substituent

A straightforward TBHP-mediated synthesis of 2-amidobenzoic acids from 2-arylindoles and their antimicrobial activity

A simple and highly efficient strategy has been developed for the synthesis of 2-amidobenzoic acids through the tert-butyl hydroperoxide (TBHP)-mediated oxygenation and sequential ring opening of 2-arylindoles in a one-pot fashion under metal-free aerobic conditions. The developed synthetic protocol is operationally simple, tolerates a wide range of functional groups, and is amenable to the gram-scale. Radical trapping experiments revealed that the reaction involves a radical pathway. The synthesized compounds (2a-s) were tested for in vitro antimicrobial activity. Among all screened compounds, 2d showed the maximum antibacterial activity against P. aerugunosa (ZOI = 17 mm, MIC = 32 μg mL-1) and compounds 2d and 2p showed the maximum (32 μg mL-1) antifungal activity against A. flavus and C. albicans.

Synthesis and characterization of quinazoline derivatives: Search for hybrid molecule as diuretic and antihypertensive agents

To explore the pharmacological and structure-activity relationship of a series of N-substituted-(4-oxo-2-substituted-phenylquinazolin-3-(4H)-yl), substituted benzene sulfonamide derivatives (1-25) were synthesized from substituted anthranilic acids derive
