摘要:
The invention belongs to the field of biomedical research involving the 1, 3, 4- selenyldiazo derivatives that have cell protective activity. Because there are not so many heterocyclic selenium compounds, we synthesized a new type of selenium analog of BPTES. As the isoacceptor of BPTES, the compounds have antitumor activity, anti-oxidation and cell protection function. Currently many drugs contain the thiodiazo motif, so synthesis of selenyldiazo functional group could further optimize these drugs and are important in new drug development and application.

Disclosed is a prodrugs of the formula (I) where A is a sulfur or a selenium, and R is derived from a mono- di- or oligosaccharide. Also disclosed is a prodrug of the formulas (II); where A is sulfur or selenium, R' is derived from a sugar and R' has the formula (CHOH)nCH2OH, where n is 1 to 5, or R' is an alkyl or aryl group, or R' is =O, and the R'' groups may be the same or different and may be hydrogen, alkyl, alkoxy, carboxy. Also disclosed is a conjugate of an antioxidant vitamin and a thiolamine or selenolamine. Also disclosed is a prodrug of the formula (III); where A is sulfur or selenium, and R' is derived from a sugar and R' has the formula (CHOH)nCH2OH, where n is 1 to 5, or R' is also an alkyl or aryl group, or R' is =O, and R is an alkoxy, or an amine group. Also disclosed is a prodrug of the formula (IV) R is COOH or H, and R' is derived from a sugar and R' has the formula (CHOH)nCH2OH, where n is 1 to 5, or R' is an alkyl or aryl group, or R' is =O.
摘要:
Optical recording media comprising a base (1), a recording layer (2) formed thereon, and a reflecting layer (3) formed on the layer (2), wherein the recording layer (2) contains at least one kind of specified dyes selected from among polymethine dyes having 1 to 4 carbon atoms in the main methine chain to secure a sufficient recording sensitivity to a light in the red wavelength region.
