Application of human PCID2 protein in preparation or screening of anti-tumor drugs and compound with anti-tumor activity

The invention belongs to the technical field of biotechnology and gene therapy, and particularly relates to application of human PCID2 protein in preparation or screening of anti-tumor drugs and an anti-tumor compound. It is found that the PCID2 gene promotes tumor cell proliferation and regulates the cell cycle, is a key molecule for regulating tumor generation and development, and can be used as a target protein for preparing or screening anti-tumor drugs; meanwhile, human PCID2 protein is used as target protein, a class of PCID2 protein targeting antitumor compounds are screened out through a molecular docking technology, and the compounds can significantly inhibit tumor cell proliferation and promote tumor cell apoptosis.

A synthetic chalcone as a potent inducer of glutathione biosynthesis

Chalcones continue to attract considerable interest due to their anti-inflammatory and antiangiogenic properties. We recently reported the ability of 2′,5′-dihydroxychalcone (2′,5′-DHC) to induce both breast cancer resistance protein-mediated export of glutathione (GSH) and c-Jun N-terminal kinase-mediated increased intracellular GSH levels. Herein, we report a structure-activity relationship study of a series of 30 synthetic chalcone derivatives with hydroxyl, methoxyl, and halogen (F and Cl) substituents and their ability to increase intracellular GSH levels. This effect was drastically improved with one or two electrowithdrawing groups on phenyl ring B and up to three methoxyl and/or hydroxyl groups on phenyl ring A. The optimal structure, 2-chloro-4′,6′-dimethoxy-2′- hydroxychalcone, induced both a potent NF-E2-related factor 2-mediated transcriptional response and an increased formation of glutamate cysteine ligase holoenzyme, as shown using a human breast cancer cell line stably expressing a luciferase reporter gene driven by antioxidant response elements.

Synthesis and antiinflammatory activity of some new 1,3,5-trisubstituted pyrazolines bearing benzene sulfonamide

Nineteen new 2-pyrazoline bearing benzenesulfonamide derivatives were synthesized by condensing chalcones with 4-hydrazinonbenzenesulfonamide hydrochloride. Their chemical structures were proved by means of IR, 1H NMR, 13C NMR, mass spectroscopic and elemental analyses data. These compounds were tested at dose of 20 mg/kg for their anti-inflammatory activity in carrageenan-induced rat paw edema model and volume of paw edema was measured at 0, 3 and 5 h. Two compounds 3k and 3l were found to be more active than celecoxib throughout the study (at 3 and 5 h). While two other compounds 3m and 3n showed more potent activity than celecoxib at 5 h. They are devoid of ulcerogenic potential when administered orally at a dose of 60 mg/kg. Compounds (3k-m) showed COX-1 and COX-2 inhibitory activity at 0.05 μM.
