Ailanthone is a quassinoid that has been found in Ailanthus and has diverse biological activities.1,2,3 It is active against the P. falciparum strains HB-3 and Dd-2 in vitro (IC50s = 0.003 and 0.037 μg/ml, respectively).1 Ailanthone is phytotoxic, inhibiting radish seed germination by 88% when used at a concentration of 1 mM.2 It inhibits dihydrotestosterone-induced androgen receptor transcriptional activity (IC50 = 69 nM in a reporter assay), as well as the growth and colony formation of LNCaP and 22RV1 androgen receptor-expressing cells, but not androgen receptor-negative PC3 and DU145 cells, when used at a concentration of 0.1 μM.3 Ailanthone (2 mg/kg) reduces tumor volume in 22Rv1, LNCaP, and VCaP castration-resistant prostate cancer (CRPC) mouse xenograft models. | [Uses]
Ailanthone has potent antineoplastic activity against anti-hepatocellular carcinoma (HCC) and has been shown to inhibit Huh7 cancer cell growth through cell cycle arrest and apoptosis in vitro and in vivo. | [Definition]
ChEBI: Ailanthone is a triterpenoid. | [in vivo]
Not only i.p. administration but also p.o. administration of Ailanthone has excellent efficiency for blocking the growth of CRPC xenografts. In pharmacokinetic studies, Ailanthone exhibits good solubility in water and good bioavailability (>20%). In addition, Ailanthone effectively suppresses CRPC tumour growth, despite not reaching a steady state of plasma drug concentration during the course of treatment[1]. |
