IRC-083927
IRC-083927 is an orally active tubulin inhibitor. IRC-083927 binds competitively to the colchicine-binding site on tubulin, inhibits tubulin polymerization, disrupts the microtubule cytoskeleton, and arrests the cell cycle at the G2-M phase. IRC-083927 can be used in research related to human cervical cancer, hormone-independent breast cancer, pancreatic cancer, prostate cancer, and small cell lung cancer.

Biological Activity
IRC-083927 (5-100 nM) hydrochloride disrupts and depolymerizes the microtubule cytoskeleton in human prostate cancer DU-145 cells[1].
IRC-083927 (72-96 h) hydrochloride inhibits the proliferation of human tumor cell lines including MIA PaCa-2, MDA-MB-231, DU-145, NCI-H69, NCI-H69/AR, NCI-H69/Lx4, A549, A549.EpoB40 and A549.EpoB480, with IC50 values ranging from 7 μM to 42 μM. It remains active against cell lines that develop resistance to standard tubulin-binding agents via efflux pumps or tubulin mutations[1].
IRC-083927 (10-20 nM; 11 days) hydrochloride inhibits endothelial cell proliferation and blocks angiogenesis in human umbilical vein endothelial cells (HUVECs) and their co-culture system with fibroblasts[1].
IRC-083927 (10-60 nM; 24 h) hydrochloride arrests the cell cycle at the G2-M phase in human non-small cell lung cancer A549 cell line and its tubulin mutation-resistant A549.EpoB40 cells[1].
IRC-083927 (5 μM; 60 min) hydrochloride inhibits tubulin polymerization in purified bovine brain tubulin[1].
IRC-083927 (20 μM; 3 h) hydrochloride competitively inhibits the binding of labeled colchicine to purified tubulin in a cell-free system[1].

-
Cell Line:A549 and A549.EpoB40 cell lines
-
Concentration:10, 30, 60 nM
-
Incubation Time:24 h
-
Result:Decreased the percentage of cells in the G0-G1 phase and caused a massive accumulation and arrest of cells in the G2-M phase in a concentration-dependent manner.
IRC-083927 (5 mg/kg; administered orally; once daily for 5 consecutive days followed by 2 days of withdrawal; treated continuously for 4 weeks) hydrochloride exerts a significant tumor growth inhibitory effect in a mouse model of subcutaneous xenografted human breast cancer[1].

-
Animal Model:athymic NCr-nu/nu (female, 4- to 6-week-old, human cervical C33-A tumor cells s.c. injected into flanks)[1]
-
Dosage:2.5 mg/kg; 5 mg/kg
-
Administration:p.o.; once daily for 5 days, 2 days off, repeated for 4 weeks
-
Result:Significantly inhibited tumor growth and reduced tumor volume with a certain degree of dose relevance at both the end of the treatment period and the end of the follow-up period.
Caused no apparent macroscopic toxicity throughout the treatment; animals did not experience weight loss or death.
-
Animal Model:athymic NCr-nu/nu (female, 4- to 6-week-old, human hormone-independent MDA-MB-231 breast tumor cells s.c. injected into flanks)[1]
-
Dosage:5 mg/kg
-
Administration:p.o.; once daily for 5 days, 2 days off, repeated for 4 weeks
-
Result:Significantly inhibited breast tumor growth, leading to stabilization of the tumor volume during the treatment period.
Induced no significant body weight loss or related adverse toxicities in the mice.
