Protein phosphatase 2C (PP2C) dephosphorylates a broad range of substrates and regulates apoptosis, stress response and growth-related pathways. In the course of screening for PP2C activators from natural sources, we isolated abietane-type diterpenes, pisiferdiol and pisiferic acid from
In the course of search for potent chitin synthase inhibitors from plant extracts, the chitin synthase 2 inhibitors, O-methyl pisiferic acid and 8,20-dihydroxy-9(11),13-abietadien-12-one which have diterpene skeleton, were isolated from the leaves of Chamaecyparis pisifera. These compounds inhibited
Carnosic acid (2), a major anti-oxidant in rosemary (Rosmarinus officinalis), was synthesized from pisiferic acid (1), the major constituent of Sawara (Chamaecyparis pisifera), via ortho-oxidation of the phenol using meta-chlorobenzoyl peroxide (mCBPO), chloroacetyl meta-chlorobenzoyl peroxide
