SH-42 is a potent and selective inhibitor of human Δ24-dehydrocholesterol reductase (DHCR24), with an IC50 of 42 nM. SH-42 can lead to a significant increase in plasma desmosterol levels of mice[1]. | [Biological Activity]
SH-42 is an inhibitor of ?24-dehydrocholesterol reductase (DHCR24; IC50 = 4.2 nM).1 It increases serum levels of desmosterol , the immediate precursor of cholesterol in the Bloch pathway, in mice when administered at a dose of 0.5 mg/animal per day. SH-42 increases levels of arachidonic acid and its metabolite prostaglandin E2 , as well as docosahexaenoic acid and its metabolites 19,20-EpDPA and 19,20-DiHDPA, in the peritoneal lavage fluid in a mouse model of peritonitis induced by zymosan A .2 | [in vivo]
SH-42 (500 μg, inject, once a day for five days) causes a significant increase in plasma desmosterol levels in mice[1]. | Animal Model: | C57BL/6 mice[1] | | Dosage: | 500 μg; daily; 5 days | | Administration: | Inject | | Result: | Did not cause acute changes in ALT and AST, no severe acute hepatotoxicity was observed, and desmosterol levels were upregulated. |
