Hh-Ag1.5 (SAG-1.5) is a potent Hedgehog (Hh) agonist (EC50: 1 nM) and Smoothened (Smo) receptor agonist, with an EC50 of 1 nM and Ki values between 0.5 and 2.3 nM for Smo. Hh-Ag1.5-mediated reprogramming breaks the quiescent state of non-injured hepatic stem cells and thus rescues liver failure. Hh-Ag1.5 induced differentiation of hiPSCs into skin precursor cells, spinal motor neurons and spinal sensory neurons.

Naftifine Hydrochloride is the hydrochloride salt form of naftifine, an allylamine derivate with synthetic broad-spectrum antifungal activity. Although the exact mechanism through which naftifine hydrochloride exerts its effect is unknown, it appears to selectively inhibit the enzyme squalene 2, 3-epoxidase, thereby inhibiting the biosynthesis of sterol. This results in a decreased amount of sterols, especially ergosterol which is the primary fungal membrane sterol, and a corresponding accumulation of squalene in fungal cells. Naftifine hydrochloride (Naftifine HCl) can be fungicidal as well as fungistatic to yeasts depending on the concentration and the organisms involved.
