17-b-Hydroxywortmannin (LY 301497)

 

Off white solid. PROTECT FROM LIGHT. PACKAGED UNDER INERT GAS. Purity: 99% by HPLC. CAS# 58053-83-1. Solubility: DMSO (100 mg/mL). Molecular Formula: C23H26O8. Molecular Weight: 430.5.

 

 

A cell-permeable Wortmannin 17β-Hydroxy analog (HWT) that acts as an irreversible PI 3-K inhibitor with an 8.4-fold higher potency than that of Wortmannin (IC50 = 0.5 and 4.2 nM, respectively) and inhibits mTOR only at much higher concentrations (IC50 = 0.193 M). Both Wortmannin and HWT covalently modify a conserved lysine residue (Lys833 in porcine PI 3-Kγ) in the PI 3-K ATP binding pocket via their electrophilic furan ring at C-20 position. HWT is shown to effectively arrest the growth of LNCaP cells (IC50 = 1.464 M) in vitro, however, its high in vivo toxicity renders it unsuitable for tumor killing studies in mice. Also reported to inhibit late phase PLD-mediated PA production upon fMLP stimulation of human neutrophils.
