In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Synthesis of New Cyanopyridine Scaffolds and their Biological Activities, published in 2020-11-30, which mentions a compound: 3326-71-4, Name is 2-Furoic hydrazide, Molecular C5H6N2O2, Safety of 2-Furoic hydrazide.
The 3-cyanopyridine analogs I, II and III [Ar = 4-methylphenyl, 4-methoxyphenyl, 4-chlorophenyl, etc.] were synthesized and examined to determine their activity against the M. tuberculosis H37Rv strain. Derivatives I [2-thienyl, 4-chlorophenyl] and II [Ar = 2-furyl, 2-thienyl]had good inhibition. Further screening was done for the highest potency against M. tuberculosis to determine the MICs. The antioxidant efficacy was evaluated via the DPPH technique matched with vitamin C as a pos. control. Some synthesized derivatives displayed good potency against bacterial activity and M tuberculosis. The antioxidant performance of these derivatives did not display scavenging efficacies compared to vitamin C. The cytotoxic activity of the synthesized derivatives was also examined various cell lines to display good cytotoxic activity in the order III > II > I.
Compound(3326-71-4)Safety of 2-Furoic hydrazide received a lot of attention, and I have introduced some compounds in other articles, similar to this compound(2-Furoic hydrazide), if you are interested, you can check out my other related articles.
