In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Immunosuppression by 9-alkyl-6-thiopurines, published in 1972, which mentions a compound: 4897-25-0, mainly applied to immunosuppression thiopurine derivative; antibody formation inhibition thiopurine, Recommanded Product: 4897-25-0.
6-Mercaptopurine [50-44-2], 9-butyl-6-mercaptopurine [6165-01-1], azathioprine [446-86-6], 9-butylazathioprine [20917-47-9], 6-methylthioinosine [342-69-8], chloroimidazole [4897-25-0], 6-thioguanine [154-42-7], 9-butyl-6-thioguanine [30546-08-8], guaneran [5581-52-2], 9-butylguaneran [36892-45-2], 6-thioguanosine [85-31-4], and 6-methylthioguanosine [34020-33-2] significantly suppressed the antibody response of mice to sheep red blood cells. Only 5-glutathionyl-1-methyl-4-nitroimidazole [36892-55-4] and 9-isobutylguaneran [36892-43-0] had no significant effect. Thus, 2 classes of 6-thiopurines have immunosuppressive activity: 9-unsubstituted derivatives which form nucleotide analogs inside cells and stable 9-alkyl derivatives which have a mechanism of action unrelated to nucleotide formation.
From this literature《Immunosuppression by 9-alkyl-6-thiopurines》,we know some information about this compound(4897-25-0)Recommanded Product: 4897-25-0, but this is not all information, there are many literatures related to this compound(4897-25-0).
