“…[8,9] Also 1,3,4-oxadiazole derivatives have been found to exhibit diverse biological activities such as antimicrobial, [10,11] anti-HIV, [12] antitubercular, [13] antimalarial, [14] anti-inflammatory, [15,16] anticonvulsant, [17] and antitumor. [18] In an earlier communication, [19] synthesis and antimicrobial studies of 2-(p-substituted aryl)-s-triazolo[5,1-b]-6/8-substituted quinolino [1,3]thiazin-9(H)-ones were reported. Quinoline derivatives carrying 1,2,4-oxadiazole moiety were synthesized and evaluated for antituberculosis studies.…”
