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

Demethyl(trifluoromethyl)actinomycins

The synthesis of new 4-(trifluoromethyl)benzoic acid derivatives 2-10 and their coupling with amino acids and peptides 12, 13, 15 is described.They serve as precursors for the synthesis of the hitherto unknown demethyl(trifluoromethyl)actinocin dimethyl esters 11, demethyl-trifluoromethyl-actinocinyl peptides 14, 16, 18 and the demethyl-trifluoromethyl-actinomycins 17.Although spacially comparable with the methyl residues, the 4- and 6-trifluoromethyl groups have unexpected strong influences on the antibiotic and cytostatic properties of the actinomycins.The CH3/CF3 exchange makes it possible to bring NMR-analytically useful hetero nuclei into the centre of the actinomycin/DNA complex (Figure 1).
