title: Quinoxaline chemistry. Part 7. 2-[aminobenzoates]- and 2-[aminobenzoylglutamate]-quinoxalines as classical antifolate agents. Synthesis and evaluation of in vitro anticancer, anti-HIV and antifungal activity.
abstract: Thirty-three quinoxalines bearing an aminobenzoyl or aminobenzoylglutamate group on position 2 and various substituents on position 3,6,7 of the heterocycle were prepared in order to evaluate in vitro anticancer activity. Preliminary screening performed at NCI showed that most derivatives exhibited a moderate to strong growth inhibition activity on various tumor panel cell lines between 10(-5) and 10(-4) Molar concentrations. Interesting selectivities were also recorded between 10(-8) and 10(-6) M. Among the series examined one compound (29) which was the most active also exhibited both in vitro anti-HIV protection and antifungal activity while in other two (31, 37) the antifungal activity was prevailing.
