| Abstract | CYP2B subfamily accounts for 2-10% of total hepatic CYP450 enzymes and participate in the metabolism of around 8% of clinical drugs. Borneol has been widely used in traditional Chinese medicine for thousands of years. There are many studies about borneol-induced promoting penetration role for a number of drugs through various physiologic barriers, whereas there is no report involved the effect of borneol on hepatic CYP2B. The present work studied the in vivo effect of borneol on the expression and activity of rat hepatic CYP2B. The results indicated that the oral administration of borneol (33, 100 and 300 mg/kg/d) to rats for consecutive 7 days increased the hepatic CYP2B1/2 activity by 1.4-, 1.7- and 2.8-fold, hepatic CYP2B1 mRNA expression by 6.3-, 8.7- and 18.1-fold, and hepatic CYP2B1/2 protein expression by 1.2-, 1.9- and 2.6-fold, respectively compared to the control. Additionally, in the borneol pre-dosing (300 mg/kg/d for consecutive 7 days) rats, the increased Cl and decreased AUC of bupropion were observed as compared to the control. Moreover, there were no obvious effects on CAR protein level in rat liver microsome and nucleus following the borneol treatment. Taken together, our observations indicate that borneol is an in vivo inducer of rat hepatic CYP2B with different regulatory mechanism from phenobarbital-like inducers which caused CYP2B induction with CAR activation. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
