Common Name

(1s,8r,9r)-1,9-bis(3,4-dihydroxyphenyl)-6,8-dihydroxy-1h,2h,7h,8h,9h,10h-naphtho[2,1-b]pyran-3-one

Description

Cinchonain I b belongs to the class of organic compounds known as prenylated neoflavonoids. These are neoflavonoids that features a C5-isoprenoid substituent at any position of the A, B, or C ring. Neoflavonoids are compounds with a structure based on the 4-phenylchromene backbone. (1s,8r,9r)-1,9-bis(3,4-dihydroxyphenyl)-6,8-dihydroxy-1h,2h,7h,8h,9h,10h-naphtho[2,1-b]pyran-3-one is found in Cinchona pubescens, Kandelia candel, Phyllocladus trichomanoides, Trichilia catigua and Uncaria tomentosa. (1s,8r,9r)-1,9-bis(3,4-dihydroxyphenyl)-6,8-dihydroxy-1h,2h,7h,8h,9h,10h-naphtho[2,1-b]pyran-3-one was first documented in 2002 (PMID: 12398535). Based on a literature review very few articles have been published on cinchonain I b.
