Description

Tamibarotene (brand name: Amnolake), also called retinobenzoic acid, is orally active, the synthetic retinoid, developed to overcome all-trans retinoic acid (ATRA) resistance, with potential antineoplastic activity against acute promyelocytic leukemia (APL). Tamibarotene is a specific agonist for retinoic acid receptor alpha/beta. It is currently marketed only in Japan and early trials have demonstrated that it tends to be better tolerated than ATRA. It has also been investigated as a possible treatment for Alzheimer's disease, multiple myeloma, and Crohn's disease.

In Vitro Use Guide
The cell viability of A549 or MRC-5 cell lines treated with Am80 or ATRA was assessed using the CellTiter-Glo Luminescent Cell Viability Assay (Promega KK, Tokyo, Japan). Cells were seeded at 625 per cm2 in 100 μL of medium in 96-welled flat-bottom plates and grown overnight at 37°C in an incubator. After exposure to Am80 for 6 d, the plates were assayed using EnVision Plate Reader (PerkinElmer, Inc. Japan Co., Ltd., Kanagawa, Japan).
