DTS-201 sodium
DTS-201 sodium (CPI-0004Na) is a peptidic prodrug of Doxorubicin (HY-15142A). DTS-201, comprising the tetrapeptide portion, is cleaved by endopeptidases in the tumor environment to produce metabolites that subsequently enter the cell and are converted to active Doxorubicin. DTS-201 shows antitumoral efficacy in tumor xenograft models of prostate, breast, and lung cancer.

Biological Activity
DTS-201 (i.v., 15 min, on day 1 and 22) sodium is well tolerated in mice (50 mg/kg, MTD) and rats (40 mg/kg, MTD)[1].
DTS-201 (3.2, 12.8 and 25.6 mg/kg, i.v., once weekly for 7 weeks) sodium shows less cardiotoxicity than Doxorubicin[1].
DTS-201 (40-80 mg/kg, i.v.) sodium has a better therapeutic index than free Doxorubicin in NCI-H1299, PC-3, and MDA-MB-231 xenograft mice[1].
