Adozelesin (U 73975, adolezesin) is an experimental antitumor drug of the duocarmycin class. Adozelesin is a highly potent alkylating agent that undergoes binding in the minor groove of double-stranded DNA (ds-DNA) at A-T-rich sequences followed by covalent bonding with N-3 of adenine in preferred sequences. Adozelesin is therapeutically active against a broad spectrum of tumours and was in phase II clinical trials with Pharmacia Corporation (now Pfizer) in the US for breast cancer treatment. Phase I and Phase II clinical trials were conducted in 2000s, however, it was found adozelesin had marginal efficacy in the treatment of metastatic breast cancer at the dosage and schedule used.

Sample Use Guides

In Vivo Use Guide

Solid tumors: Adozelesin was given as a 10 minute IV infusion for 5 consecutive days every 21 days or upon recovery from toxicity. The dose range evaluated was 6-30 mcg/m2/day. The maximum tolerated dose was 30 mcg/m2/day. The recommended Phase II starting dose of Adozelesin using a 10 minute IV infusion for 5 consecutive days is 25 mcg/m2/day to be repeated every 4-6 weeks to allow recovery from myelotoxicity, based on our experience.

Route of Administration: Intravenous

In Vitro Use Guide

In human colon carcinoma HCT116 cells low adozelesin concentrations (e.g., 0.5 nM) induced a transient S-phase block and cell cycle arrest in G(2)-M, as well as increased induction of p53 and p21, whereas a high drug concentration (e.g., 2.5 nM) caused apoptosis but no p21 induction.
