New marine-derived indolymethyl pyrazinoquinazoline alkaloids with promising antimicrobial profiles
Due to the emergence of multidrug-resistant pathogenic microorganisms, the search for novel antimicrobials is urgent. Inspired by marine alkaloids, a series of indolomethyl pyrazino [1,2- b ]quinazoline-3,6-diones was prepared using a one-pot microwave-assisted multicomponent polycondensation of ami...

were the most effective against
Staphylococcus aureus
ATCC 29213 reference strain with MIC values of 4 μg mL
