/* GSK-3 Inhibition Mechanism - Phosphorylation */
'''Key Finding'''
* '''Pyrazole compounds with inhibition constant (Ki) of <0.1 mM''' are a good starting point for developing molecules that can inhibit serine/threonine protein kinase (such as GSK-3) and the proteins they help to regulate.

=== Pathway associated with anti-androgen ===
* Dihydrotestosterone
** Formed by peripheral conversion of testosterone by 5-alpha reductase
** Binds to androgen receptor on susceptible hair follicles
* Hormone-receptor complex activates genes responsible for gradual transformation of large terminal follicles to miniaturized (progressive diminution of hair shaft diameter and length in response to systemic androgens) follicles

=== Pathway associated with Minoxidil (vasodilators) ===
Minoxidil is a well know drug used for the treatment of alopecia. A co-relation between Sesquiterpene lactone (Helenalin) produced from Arnica montana and Minoxidil is illustrated in the figure below. Arnica montana, a Vasodilator, acts on the NO/cGMP Pathway through T-cells, B-cells and epithelial cells & abrogates kappa B-driven gene expression.
