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).

The effect of 2-mercaptoethanol (2-ME) and alpha-thioglycerol (alpha TG) on proliferation and polyclonal activation of lymphocytes was studied in cultures of spleen cells from C3H mice. Inclusion in serum-free or serum-containing medium of the optimal concentration (5 x 10(-5) M)

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)

Thiol-modified surfaces are chemically well defined and suited for surface biological model experiments and biomaterials research. 3-Mercapto-1,2-propanediol (mercaptoglycerol, MG), immobilized on gold, spontaneously binds immunoglobulins from human serum and activates the complement system. The surface-bound complement factors were detected by

Since the realization of a complement activation capacity by artificial surfaces upon contact with blood, a common belief has evolved that charged nucleophilic surface groups such as amine (-NH2) and hydroxyl (-OH) react with and eventually bind to the internal

A new enzyme-labile group called S-acyl-3-thiopropyl group (SATP) has been synthesized from allylic esters of phosphonate. After demonstration of the enzyme-labile character of the SATP in cellular extracts, it has been introduced onto the phosphonate moiety of PFA (Foscarnet) to
