Paragraph 0076; 0084-0085, (2021/06/09)
The invention provides a phthalimide compound or a pharmaceutically acceptable salt thereof, wherein the structure of the phthalimide compound is shown as a formula I; in the formula I, R1 is selected from hydrogen, aliphatic hydrocarbon, alkoxy and halogen; R2 and R3 are the same or different and are selected from hydrogen, aliphatic hydrocarbon, alkoxy and halogen; or R2, R3 and connected N atoms are cyclized to form a closed substituted or unsubstituted five-membered or six-membered ring; R1, R2 and R3 can be unsubstituted or substituted by straight chain or branched chain alkyl or alkoxy selected from C1 - C10 and halogen; and R1, R2 and R3 are not hydrogen at the same time. The compound disclosed by the invention has the effect of a ROCK inhibitor and an anti-tumor effect, and is expected to be used as a clinical medicine with a relatively high therapeutic index.

This work reports the first application of diarylthiazolidin-2,4-diones as nucleophiles in asymmetric catalysis. By utilizing chiral amino acid-based (thio)urea-tertiary amines as the catalysts, we successively established asymmetric conjugate addition to nitroolefins and sulfenylation to N-(sulfanyl)-succinimides of diarylthiazolidin-2,4-diones. Two series of biologically important 5-aryl-5-substituted thiazolidin-2,4-diones were obtained with high enantio- and diastereoselectivities (up to >99% ee and >19:1 dr). The enantioenriched adducts were found to show satisfactory anticancer activities against three different cancer cell lines using the MTT assay. All of these successes depended on the development of a general and expedient synthetic strategy to provide diverse 5H-thiazolidin-2,4-diones.
