Biochem/physiol Actions

ATR-101 (PD 132301-02; Nevanimibe HCl) is an orally active, potent and selective acyl-CoA:cholesterol acyltransferase 1 (ACAT1, SOAT1) inhibtior (IC50 = 52 nM; intestinal microsome from cholesterol-fed rabbits) that reduces plasma cholesterol in both acute (by 77%; 50 mg/kg po.) and chronic (by 80%; 10 mg/kg po.) cholesterol-fed rat models. In addition, ATR-101 is reported to exhibit therapeutic efficacy against adrenocortical carcinoma (ACC), congenital adrenal hyperplasia (CAH), and Cushing′s syndrome (CS).

To assess whether previously reported ultrastructural alterations of adrenocortical mitochondria induced by the acyl-CoA:cholesterol acyltransferase (ACAT) inhibitor PD 132301-2 are accompanied by functional deficits in tissue energy stores, phosphorylated adenine nucleotide levels in guinea pig adrenal cortex were quantitated. Adrenals

PD132301-2, an inhibitor of acyl-coenzyme A:cholesterol O-acyltransferase (ACAT; EC 2.3.1.26), and 1-stearylboronic acid (SBA), a fatty acid analogue, were orally administered to White Leghorn hens in separate experiments to evaluate their effects on layer performance and plasma and egg yolk

A novel lipid regulator (PD132301-2) produces degeneration and necrosis of adrenal fasciculata in guinea pigs. Primary adrenocortical cell cultures from male Hartley guinea pigs were utilized to investigate potential mechanisms of this toxicity. Concentration-dependent loss of viability, measured by neutral

PD132301-2, a novel inhibitor of acyl-CoA: cholesterol acyltransferase, was previously shown to be an inhibitor of mitochondrial respiration and an adrenal toxicant in several species. To investigate potential mechanisms of tissue-specific toxicity in vivo, dog adrenocortical and hepatocyte cell cultures

Endocrinology, 157(5), 1775-1788 (2016-03-18)
ATR-101 is a novel, oral drug candidate currently in development for the treatment of adrenocortical cancer. ATR-101 is a selective and potent inhibitor of acyl-coenzyme A:cholesterol O-acyltransferase 1 (ACAT1), an enzyme located in the endoplasmic reticulum (ER) membrane that catalyzes
