antitumor agent-40

Antitumor Agent-40 serves as a research chemical for investigating cancer [1].

cDPCP is a platinum-containing DNA-crosslinking agent.1Unlike cisplatin or oxaliplatin , cDPCP forms monofunctional DNA adducts. It is transported into cells by organic cation transporter 1 (OCT1) and OCT2, inhibiting proliferation of MDCK cells expressing the human transporters with IC50values of 8.1 and 1.5 μM, respectively. cDPCP inhibits RNA polymerase II-mediated transcription in a reporter assay using HeLa cells. It increases survival in murine S180 sarcoma and P388 leukemia models when administered at doses of 40 and 80 mg/kg, respectively.2 1.Lovejoy, K.S., Todd, R.C., Zhang, S., et al.cis-Diammine(pyridine)chloroplatinum(II), a monofunctional platinum(II) antitumor agent: Uptake, structure, function, and prospectsProc.

Antitumor Agent-63 (Compound 40), a 20 (S)-O-linked camptothecin (CPT) glycoconjugate, serves as a non-toxic antitumor agent showing high stability and very weak direct inhibition of topoisomerase I (Topo I) [1], demonstrating selective action without harming normal cells.

Antitumor agent-119 (compound 13K), a 2-benzoxazolyl hydrazone derivative, exhibits anticancer capabilities by impeding the proliferation of Burkitt, CCRF-CEM, HeLa, and HT-29 cells, with respective IC50 values of 30 nM, 140 nM, 100 nM, and 40 nM [1].
