In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 49679-45-0, name is Ethyl 3-chloroquinoxaline-2-carboxylate, introducing its new discovery.

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
Thirty-three quinoxalines bearing an aminobenxoyl or aminobenzoylglutammate 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. 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.
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 49679-45-0, and how the biochemistry of the body works.Safety of Ethyl 3-chloroquinoxaline-2-carboxylate
