Application

1-Thioglycerol, a derivatization reagent, is used to study the pH-sensitive photoluminescence of aqueous thiol-capped CdTe nanocrystals. 1-Thioglycerol is used to develop and test thiol-functionalized copolymers. 1-Thioglycerol is used as a post-modification agent in the generation of non-standard peptide foldamers.Potential substitute for 2-mercaptoethanol; probe for the study of lymphocyte activation.

Preparation Note

This product is miscible in ethanol (1 ml/ml, 50%, v/v), yielding a clear, colorless solution. It is also miscible in water (0.1 M).

Biomaterial-mediated complement activation repeatedly has been invoked as a trigger of phagocyte reactions and inflammation. However, a direct correlation between complement activation and inflammatory responses to biomaterial surfaces has yet to be established. Using an animal implantation model and gold

Cloretazine (VNP40101M; 101M; 1,2-bis(methylsulfonyl)-1-(2-chloroethyl)-2-[(methylamino)carbonyl]hydrazine) is a sulfonylhydrazine prodrug that generates both chloroethylating and carbamoylating species on activation. To explore the molecular mechanisms underlying the broad anticancer activity observed in preclinical studies, cloretazine and chloroethylating-only [i.e., 1,2-bis(methylsulfonyl)-1-(2-chloroethyl)hydrazine] and carbamoylating-only (i.e., 1,2-bis(methylsulfonyl)-1-[(methylamino)carbonyl]hydrazine)
