It has been reported that pantothenic acid (vitamin B5) and panthenol, an alcohol derivative of pantothenic acid, have beneficial moisturizing effects on the skin. However, few studies have investigated the mechanism of action of pantothenic acid on skin tissues. We tried to clarify the role of pantothenic acid on skin function by using keratinocytes and fibroblasts. The depletion of pantothenic acid from the culture medium suppressed keratinocyte proliferation and promoted differentiation. Moreover, pantothenic acid depletion decreased the synthesis of keratinocyte growth factor and procollagen 4a2 in fibroblasts. These results suggest that pantothenic acid is essential for maintaining keratinocyte proliferation and differentiation. © The Japanese Pharmacological Society. Source

Preparations and in vitro antifungal activities of triazolopyridines, imidazopyridines, and a pyrazolopyridine were reported. Among those scaffolds, triazolopyridine was found to be the specific inhibitor of the synthesis of β-1,6-glucan, an essential component of the fungal cell wall, and to show potent antifungal activities against several Candida species. © 2010 Elsevier Ltd.
