In this study, we introduced 1, 2, 4-triazole groups into panaxadiol (PD) to obtain 18 panaxadiol triazole derivatives. Five cancer cells and one normal cell were evaluated for cytotoxicity by MTT assay. The results showed that most of the derivatives could inhibit cancer cell proliferation, and the anti-proliferative activity of compound A1 was the most significant. For HepG-2 cells, the IC50 value was 4.21 ± 0.54 μM, which was nearly 15 times higher than the activity of PD. Further studies showed that compound A1 could induce apoptosis in HepG-2 cells, and could enhance the expression of Cl-caspase-3, Cl-caspase-9 and Cl-PARP. Moreover, Western blot analysis showed that after treating HepG-2 cells with compound A1, the expression of p53 protein was increased and the ratio of Bax/Bcl-2 was gradually increased. The cytoplasmic Bax is then translocated to the mitochondria, causing the release of Cyt c protein. Therefore, the results indicate that compound A1 induces apoptosis through the mitochondrial pathway and can be used the potential to develop new anti-proliferative agents.

A series of diethyl (3-((5-aryl-1H-1,2,4-triazol-3-yl)thio)propyl)phos-phonates (7a-t) has been synthesized in excellent yields by coupling diethyl (3-bromopropyl)phosphonate and 5-aryl-1H- 1,2,4-triazol-3-thiones employing an efficient, green and nonconventional heterogeneous SO3Hcarbon catalyst derived from glycerol. In addition, a facile and green approach for the esterification of carboxylic acids by utilizing glycerol-based solid acid catalyst has been reported. Structures of the synthesized compounds were characterized by IR, NMR and HRMS studies. These triazole derivatives were screened for their in vitro cytotoxicity using the standard MTT (3-(4,5-dimethylthiazol-2- yl)-2,5-diphenyltetra-zolium bromide) assay against a panel of five different human cancer cell lines (HeLa: Cervix, A549: Lung, A375: Skin, MDA-MB-231: Breast and T98G: Brain). The antimicrobial activities of the synthesized compounds were investigated against four bacterial strains: Bacillus subtilis, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and three fungal strains: Aspergillus Niger, Aspergillus terreus, Aspergillus fumigatus. Preliminary results indicate that the compound 7f displayed maximum anticancer activity and the compounds 7d, 7e, 7f, 7m and 7q exhibited moderate antibacterial activity. The compounds 7g, 7h, 7o and 7p showed good antifungal activity with high inhibition zone diameter compared to the standard drug.

A series of 5-Aryl-1H-1,2,4-triazole-3-thiol (3) were synthesized. Alkylation of thiol group with N,Ndimethyl/ diethyl/dicyclo hexyl-(2-chloro ethyl) amine gave compounds N,N-disubstituted-2-(5-Aryl-1H-1,2,4-triazol-3- ylthio)ethanamine (4). These compounds were characterized on the basis of IR, 1H NMR, Mass spectral data, and elemental analysis. The newly synthesized compounds were screened for their antidepressant activity by using tail suspension test in mice. Springer Science+Business Media, LLC 2011.

The synthesis of some aroylisothiosemicarbazides was accomplished and their biological activity against bacteria, fungi, and mycobacteria was investigated. Different synthetic pathways were followed according to the kind of substituents that were introduced on both the aroyl ring and the sulfur atom. Anti-bacterial activity was measured against Staphylococcus aureus, S. epidermidis, Streptococcus agalactiae and S. faecalis, Escherichia coli, and Salmonella typhi, while antifungal activity was evaluated against C. albicans. Two species, Mycobacterium tuberculosis H37RV and Mycobacterium avium ATCC19421, were employed to evaluate antimycobacterial activity.
