8 Amazing Things Relating To cdk1 inhibitor Cell Cycle inhibitor

Making use of the reporter gene assay and polymerase chain reaction cdk1 inhibitor Yu et al. observed that tanshinone IIA and cryptotanshinone had been efcacious pregnant X receptor agonists, and that constitutive androstane receptor and glucocorticoid receptor had been, to a lesser extent, associated with the induction of CYP3A4 expression by tanshinones.

While these ndings suggested that the lipophilic components of danshen cdk1 inhibitor extract might account for danshen mediated CYP3A4 induction, no human studies have investigated the potential of danshen to alter drug metabolism of CYP3A substrates. The probable interaction between the lipophilic Cell Cycle inhibitor components of danshen tablets and substrates of CYP3A has not been investigated. The purpose of this study was to investigate whether danshen tablets could induce CYP3A4 activity using midazolam, which is recognized as one of the preferred in vivo probes, in healthy volunteers. This nding could provide useful insight into the safe and effective use of danshen preparations in clinical practice. Danshen tablets used in this study were produced according to the method in the Chinese Pharmacopoeia and contained an extract of 1 g danshen, manufactured by Shanghai Leiyongshang Pharmaceutical Limited Company.

Subjects were excluded from participation if they had any relevant medical history or had consumed any known or suspected inhibitors or inducers of CYP enzymes within 4 weeks of the commencement of the study. The use of any Cell Cycle inhibitor other drugs, herbal or dietary supplements, and grapefruit juice was prohibited throughout the study. Study design The study design was a sequential, openlabel, two period trial conducted at the Drug Clinical Research Organization of Yijishan Hospital. On the morning of day 1, after fasting overnight, a single dose of 15 mg midazolam was administered orally. The volunteers were provided a light standard meal at 4 h and 10 h after medication intake. At 10 and 12 h after drug administration 4 ml of blood were obtained from forearm veins for measurement of midazolam and 1 hydroxymidazolam.

Extraction of midazolam and 1 hydroxymidazolam was performed with 0. 2 ml plasma, diluted with 30 l of 1 M NaOH solution and 10 l of diazepam solution, to which 1 ml of ethyl acetate was added. The samples were centrifuged, evaporated and reconstituted in the mobile phase.
