The triazine antitubercular JSF-2019 was of interest due to its in vitro efficacy and the nitro group shared with the clinically relevant delamanid and pretomanid. JSF-2019 undergoes activation requiring F420H2 and one or more nitroreductases in addition to Ddn. An intrabacterial drug metabolism (IBDM) platform was leveraged to demonstrate the system kinetics, evidencing formation of NO? and a des-nitro metabolite. Structure-activity relationship studies focused on improving the solubility and mouse pharmacokinetic profile of JSF-2019 and culminated in JSF-2513, relying on the key introduction of a morpholine. Mechanistic studies with JSF-2019, JSF-2513, and other triazines stressed the significance of achieving potent in vitro efficacy via release of intrabacterial NO? along with inhibition of InhA and, more generally, the FAS-II pathway. This study highlights the importance of probing IBDM and its potential to clarify mechanism of action, which in this case is a combination of NO? release and InhA inhibition. Wang et al. disclose the optimization of a triazine antitubercular agent and probe its mechanism of action. They demonstrate the significance of studying intrabacterial drug metabolism. Through this approach and other methods, they evidence a novel mechanism involving NO? release and inhibition of the cell wall biosynthesis enzyme InhA.

We herein report a new small library of Schiff-base compounds that encompasses s-triazine and (2 or 4)-hydroxylbenzylidene derivatives. These compounds were synthesized through a hydrazone linkage connecting both the s-triazine and hydroxybenzylidene deri

1,3,5-Triazines and pyrimidine-2,4,6-triones belong to that class of compounds which are well known in literature for possessing wide range of biological activities. Here, we report a new family of compounds that encompasses these two structures. The unio

s-Triazine is considered a privileged structure, as it is found in several FDA-approved drugs. In the framework of our ongoing medicinal chemistry project based on the use of s-triazine as a scaffold, we synthesized a series of mono- and di-pyrazolyl-s-triazine derivatives and tested them against four human cancer cell lines, namely Human breast carcinoma (MCF 7 and MDA-MB-231), hepatocellular carcinoma (HepG2), colorectal carcinoma (LoVo), and leukemia (K562). The cell viability assay revealed that most of the s-triazine compounds induced cytotoxicity in all four types of human cancer cell lines, however, compounds 4a, and 6g, both of them have a piperidine moiety in their structure were most effective. These two compounds affected the cell viability of cancer cells, with IC50 values within the range between 5 to 9 μM. The cell cycle analysis showed that 4a and 6g induced S and G2/M phase cell cycle arrest in K562 cells. This could be the mechanism by which these molecules induced cytotoxicity in tested cancer cells. The prepared compounds were tested in zebrafish embryos to evaluate in vivo and developmental toxicity of the pyrazolyl-s-triazine derivatives in animals. None of the derivatives were lethal in the concentration range tested.
