Antitumor agent-28 is a compound that specifically targets and inhibits the activity of the ataxia telangiectasia mutated (ATM) kinase. By doing so, it effectively impedes the progression of ATM-mediated diseases and demonstrates significant anti-cancer activity.
Antitumor agent-23 exhibits potent antitumoral activity, as demonstrated by its GI50 values of 38, 48, 5, 27, 80, and 28 nM against the lymphoma cell lines GRANTA-519, KARPAS-422, KARPAS-299, RAMOS, DAUDI, and RAJI respectively.
CB 300919 is a quinazoline-based antitumor agent with high activity in the CH1 human ovarian tumor xenograft and has continuous exposure (96 h) growth inhibition (IC50: 2 nM).
Duocarmycin A, an antitumor antibiotic, is a DNA alkylator and efficiently alkylates adenine N3 at the 3′ end of AT-rich sequences in the DNA. Duocarmycin A, as a chemotherapeutic agent, results in HLC-2 cells typically apoptotic changes.
