8-Nitrobenzothiazinones (BTZs) are a promising class of antimycobacterial agents currently under investigation in clinical trials. Starting from thiourea derivatives, a new synthetic pathway to BTZs was established. It allows the formation of the thiazinone ring system in one synthetic step and is applicable for preparation of a wide variety of BTZ analogues. The synthetic procedure furthermore facilitates the replacement of the sulphur atom in the thiazinone ring system by oxygen or nitrogen to afford the analogous benzoxazinone and quinazolinone systems. 36 BTZ analogues were prepared and tested in luminescence-based assays for in vitro activity against Mycobacterium tuberculosis (Mtb) using the microdilution broth method and a high-throughput macrophage infection assay.

A number of novel chromone derivatives containing sulfonamide moieties were designed and synthesized, and the activity of compounds against tomato chlorosis virus (ToCV) was assessed using the ToCVCP-oriented screening method. Comparative molecular field analysis (CoMFA) and comparative molecular similarity index analysis (CoMSIA) models were established based on the dissociation constant (Kd) values of the target compounds, and compound 35 was designed and synthesized with the aid of CoMFA and CoMSIA models. The study of affinity interaction indicated that compound 35 exhibited excellent affinity with ToCVCP with a Kd value of 0.11 μM, which was better than that of the positive control agents xiangcaoliusuobingmi (0.44 μM) and ningnanmycin (0.79 μM). In addition, the in vivo inhibitory effect of compound 35 on the ToCVCP gene was evaluated by the quantitative real-time polymerase chain reaction. ToCVCP gene expression levels of the compound 35 treatment group were reduced by 67.2%, which was better than that of the positive control agent ningnanmycin (59.5%). Therefore, compound 35 can be used as a potential anti-ToCV drug in the future.

A library of substituted (1-(benzyl)-1H-1,2,3-triazol-4-yl)(piperazin-1-yl)methanone derivatives were designed, synthesized and screened for their in vitro cytotoxic activity against BT-474, HeLa, MCF-7, NCI-H460 and HaCaT cells by employing 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Among all the synthesized analogues, compound 10ec displayed the highest cytotoxicity with the IC50 value of 0.99 ± 0.01 μM towards BT-474 cancer cell line. The target compound (10ec) was also evaluated for its tubulin polymerization inhibition study. Detailed biological studies such as acridine orange/ethidium bromide (AO/EB), DAPI and annexin V-FITC/propidium iodide staining assay suggested that compound 10ec induced the apoptosis of BT-474 cells. The clonogenic assay revealed that the inhibition of colony formation in BT-474 cells by 10ec in concentration-dependent manner. Moreover, the flow cytometric analysis revealed that 10ec induced apoptosis via cell cycle arrest at the sub-G1 and G2/M phase. In silico studies of sulfonyl piperazine-integrated triazole conjugates unveil that they possess drug-like properties. According to the molecular modelling studies, compound 10ec binds to the colchicine binding site of the tubulin.
