Description: Adarotene, also known as ST1926, is an atypical retinoid and a promising anti-tumour agent with selective apoptotic activity on the leukaemic blast. The anti-tumour activity of the compound has been associated with its capacity to induce DNA double stranded breaks. (source: Eur J Cancer. 2012 Dec 11. pii: S0959-8049(12)00909-4.).
