<p>N-(5-Aminopentyl) methotrexate amide-LC-biotin is a specialized bioconjugate, derived through the conjugation of methotrexate, an established antifolate drug, with an LC-biotin moiety. This product is synthesized by covalently linking methotrexate, which is known for its role in cancer therapy through the inhibition of dihydrofolate reductase (DHFR), to a biotin moiety via a long-chain spacer. The resultant bioconjugate retains the therapeutic effects of methotrexate, particularly in its ability to interrupt nucleotide synthesis, thereby affecting cell division in rapidly proliferating cancer cells.The inclusion of biotin in the structure allows for facile attachment to avidin or streptavidin-labeled systems, facilitating targeted delivery and enhanced detection in molecular and cellular studies. The primary application of N-(5-Aminopentyl) methotrexate amide-LC-biotin lies in the realm of targeted drug delivery and advanced research into methotrexate metabolism.
