Ovarian/Uterine Cancer

SEQ-1274 Drug Platform

A novel molecule class to inhibit ovarian and other cancer cell growth

SEQ-1274 is a chemically synthesized analogue of a new compound discovered using our platform technology.1 We are developing this and other novel small molecules from this platform as a potential treatment for serious, high-grade ovarian and potentially other cancers.

How it works

An inside look at SEQ-1274

SEQ-1274 is a novel microtubule inhibitor that binds to the colchicine-binding site on tubulin, a protein and main component for forming microtubules (hollow fibers that act as skeletal structures for living cells).

SEQ-1274 and analogs are potently active against over 50 human cancer cell lines (including ovarian, lung, breast, colon, central nervous system (CNS), melanoma, prostate, renal, and uterine), including several taxane-resistant cell lines. It is 5-1000 times more active than paclitaxel in a number of these cell lines.

Preclinical studies

SEQ-1274 compared to paclitaxel (taxane) in animal tumor models

SEQ-1274 has demonstrated efficacy in animal tumor models performed at four independent laboratories. Washington University researchers led by Dr. Katherine C. Fuh recently examined the potential of SEQ-1274 in the arsenal against ovarian and uterine cancers. The group compared SEQ-1274 to paclitaxel, a microtubule inhibitor, and found that SEQ-1274 was more active against ovarian and uterine cancer cell lines and that SEQ-1274 can decrease the expression of AXL, a protein contributing to paclitaxel resistance.
