Tyrosinase and its related proteins are responsible for pigmentation disorders, inhibiting tyrosinase is an established strategy to treat hyperpigmentation. The carbonyl scaffolds can be effective inhibitors of activity, the fact that both benzoic cinnamic acids safe natural substances with such a scaffolded structure, it was speculated hydroxyl-substituted acid derivatives may exhibit potent inhibitory activity. These moieties were incorporated into new chemotypes displayed in vitro effect...

Abstract The Indian pangolin ( Manis crassicaudata ) is an “endangered” mammal species that restricted to four range countries of Asia. ecology and breeding behavior pangolins poorly understood due a lack scientific data. Due heavy poaching illegal killing, the population has declined drastically in last decade. Considering fact low reproductive output, it needs special conservation measures authentic information about its ecology. We estimated concentrations three hormones from scats using...
