Legubicin
Based on 1 Customer Validation
Legubicin (Doxorubicin-LNAA-Boc) is a novel conjugate of Doxorubicin (HY-15142A) and a Legumain-cleavable peptide linker. Legubicin is activated by Legumain to release leucine-doxorubicin while sparing normal tissues. Legubicin inhibits tumor cell growth and reduces DNA binding in non-legumain expressing cells. Legubicin completely arrests tumor growth in mice bearing CT26 tumors. Legubicin can be used for the study of colon carcinoma (CRC).

Biological Activity
Legubicin (i.v., single dose, 56-day observation) shows higher MTD than conventional Doxorubicin (HY-15142A) in female SD rats and in beagle dogs, with milder toxicity signs[1].
Legubicin (5-25 mg/kg, i.v., once weekly, 4 weeks) induces dose-dependent toxicity in SD rats[1].
Legubicin (3/1.5-20/10 mg/kg, i.v., once weekly, 4 weeks) causes 80% mortality at 20/10 mg/kg in beagle dogs[1].
Legubicin (5-50 mg/kg, i.p., 2-day intervals, 3 times) completely arrests tumor growth without evident toxicity in Balb/C mice bearing CT26 tumors or WEHI nude mice bearing legumain293[2].
