mdamb-231

PRIMA-1 (NSC-281668) is a mutant p53 reactivator that induces apoptosis and inhibits the growth of human tumors with mutant p53.

Pinostrobin chalcone, a chalcone analog isolated from the leguminous plant, Mucuna pruriens, exhibits anticancer activity with an IC50 value of 20.42±2.23 μg mL against MDA-MB-231 and 22.51±0.42 μg mL against the HT-29 colon cancer cell line.

ON1231320 (GBO-006) is a Polo-like kinase 2 (PLK2) inhibitor.

Aromatase-IN-4 (Compound 6a) is an inhibitor of the enzyme aromatase. It displays anticancer properties, with GI50 values for different cell lines as follows: 2.95 μM for MDAMB-231, 3.35 μM for MCF-7, 2.27 μM for A-549, 8.46 nM for NCI-H23, and 1.56 μM for A-498. Aromatase-IN-4 effectively blocks the estrogen production that depends on aromatase.

Antitumor agent-195 (compound 16c) is a dual-targeting agent that simultaneously targets STAT3 and NQO1. At a concentration of 1 μM, it significantly inhibits the phosphorylation of STAT3 at the Tyr705 site and effectively induces apoptosis in MDA-MB-231 and MDA-MB-468 breast cancer cells. As a substrate of NQO1, Antitumor agent-195 markedly increases ROS production, causing severe DNA damage in a dose-dependent manner. It also demonstrates strong antitumor properties in MDA-MB-231 xenograft models.

Protoapigenone, an antineoplastic agent extracted from ferns, demonstrates notable inhibitory activity against various cancer cell lines, including Hep G2, Hep 3B, MCF-7, A549, and MDAMB-231. The respective IC50 values are 1.60, 0.23, 0.78, 3.88, and 0.27 μg mL [1].
