Anticancer agent 303

Anticancer agent 303 is a selective, orally active anticancer agent belonging to the pyrazolopyridine derivatives. Anticancer agent 303 exhibits low cytotoxicity to healthy cells, with a selective window of approximately 2-fold between cancer cells and healthy cells. Anticancer agent 303 produces detectable systemic exposure in mice following intraperitoneal or oral administration. Anticancer agent 303 effectively inhibits the proliferation of prostate cancer and breast cancer cells.

Biological Activity

Description

In Vitro

Anticancer agent 303 (compound 17) (5 μM; 72 h) inhibits the viability of PC-3, MCF-7 and HUVEC cells, with mean IC₅₀ values of 4.8 μM, 3.9 μM and 8.7 μM, respectively^[1].
Anticancer agent 303 (5 μM; 1-24 h) accumulates in PC-3 cells in a time-dependent manner, reaching a level of 245.8 ng/40,000 cells (104.5% of the initial administered dose) after 24 h of treatment at 5 μM^[1].

In Vivo

Anticancer agent 303 (compound 17) achieves systemic exposure in mice via intraperitoneal (i.p.) and oral (p.o.) administration. Intraperitoneal injection yields higher systemic exposure than oral administration, as indicated by increased Cmax and AUC, and has a shorter time to peak concentration (Tmax), while the elimination half-lives of the two administration routes are similar. In addition, the dose-normalized relative oral bioavailability of Anticancer agent 303 is 29.13%^[1].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
