Title: 5-Thio-D-glucose
CAS Registry Number: 20408-97-3
CAS Name: 5-Thio-a-D-glucopyranose
Additional Names: a-D-glucothiopyranose
Molecular Formula: C6H12O5S
Molecular Weight: 196.22
Percent Composition: C 36.73%, H 6.16%, O 40.77%, S 16.34%
Literature References: The nearest analog of normal D-glucose available to date. Thought to interfere with cellular transport systems utilizing D-glucose due to this structural similarity. The first chemical other than a hormone or alkylating agent which can interfere reversibly with spermatogenesis and which also has been effective against malignant cultured cells. Prepn: M. S.
