Activation of insulin-like growth factor I receptor-mediated pathway by ginsenoside Rg1.

abstract：:1 Twenty-two compounds classified as antidepressants, metabolites of antidepressants or putative antidepressants were assayed for their ability to antagonize the binding of (-)-[3H]-quinuclidinyl benzilate to muscarinic receptors in homogenates of human caudate nucleus. 2 Sixteen of these compounds were assayed for th...
