Overview

Information

ARQ 621 ARQ 621 is an allosteric, and selective Eg5 mitotic motor protein inhibitor. Phase 1.


Targets

Eg5 mitotic motor protein


In vitro

ARQ 621 demonstrates anti-tumor activity against a wide range of human cancer cell lines including colon, lung, endometrial, bladder, and hematologic cancer cell lines, with significantly less cytotoxicity against hematopoietic cells.


In vivo

ARQ 621, as a novel clinical stage drug candidate, inhibits a number of xenografts grown in athymic mice, such as pancreatic, breast, prostate, and ovarian carcinomas with no hematological changes. Furthermore, for ARQ 621, there is no envidence of bone marrow toxicity in pre-clinical mouse efficacy models or safety studies in rats and dogs.
