- Discovery of Natural Product-Based Fungicides (II): Semisynthesis and Biological Activity of Sarisan Attached 3-Phenylisoxazolines as Antifungal Agents
-
Many phytopathogenic fungi cause severe damage to crop yields. In continuation of our research aimed at the discovery and development of natural products-based fungicides, a series of thirty-one sarisan attached 3-phenylisoxazolines were synthesized and evaluated for their antifungal activities against five phytopathogenic fungi (B. cinerea, C. lagenarium, A. solani, F. solani, and F. graminearum). Among all title sarisan derivatives, compounds IV2, IV14 and IV23 showed potent antifungal activity against some phytopathogenic fungi. In particular, compound IV2 exhibited a broad-spectrum and more potent antifungal activity against A. solani, F. solani, and F. graminearum than the commercial fungicide Hymexazol. In addition, compounds IV2, IV14 and IV23 also displayed relative low toxicity on normal NRK-52E cells. This work will give some insights into the development of sarisan derivatives as new fungicide candidates in plant protection.

- Synthesis and antiproliferative properties of isoxazole analogs containing dibenzosuberane moiety
-
A series of twelve novel isoxazole analogs containing dibenzosuberane moiety were synthesized using convergent synthesis approach. Newly synthesized compounds were well characterized by mass spectroscopy, IR and NMR spectroscopy. All the compounds were screened for their antiproliferative property against HepG2 and HeLa cell lines. Among them, compounds 7a, 7b, 7c, 7g and 7h were found active against both HepG2 and HeLa cell lines. Graphical Abstract: Twelve analogs of isoxazole containing dibenzosuberane moiety (7a-l) were synthesized, characterized and evaluated for their antiproliferative activity.

- Fragment-based discovery of JAK-2 inhibitors
-
Fragment-based hit identification coupled with crystallographically enabled structure-based drug design was used to design potent inhibitors of JAK-2. After two iterations from fragment 1, we were able to increase potency by greater than 500-fold to provide sulfonamide 13, a 78-nM JAK-2 inhibitor.
