Grapefruit juice is an inhibitor of the cytochrome P450 (CYP) 3A4 enzyme system, one of the enzyme systems responsible for the metabolism of colchicine. This study will evaluate the effec...
CP-945,598 is eliminated primarily by enzyme CYP3A. Grapefruit juice may affect the activity of CYP3A and alter the amount of CP-945,598 in the blood. This study will therefore compare the...
In this prospective pharmacokinetic we investigate the following topics: - The influence of grapefruit juice and orange juice on the steady-state pharmacokinetics of sunitinib in ...
Similar to the well publicized "grapefruit juice effect", ongoing studies are evaluating the interaction potential of other dietary substances on drug disposition. This study is designed t...
The purpose of this study is to find out about the safety and effectiveness of the study drug, sirolimus, in patients with uveitis and to utilize the potential effectiveness of sirolimus, ...
The aim of this research was to evaluate the storage stability (5 °C), and microbial modeling, of Rubi red grapefruit (Citrus × paradisi) juice treated with ultraviolet-C (UV-C) light (0, 10 a...
Perivascular epithelioid cell tumor (PEComa) is a family of mesenchymal tumors. Conventional chemotherapy has little activity in this disease, but case reports are available on the activity of mammali...
Simultaneous electrokinetic and hydrodynamic injection (SEHI) and sequential stacking featuring sweeping for signal amplification following MEKC during the analysis of rapamycin (sirolimus) in serum samples.
Simultaneous electrokinetic and hydrodynamic injection (SEHI) of rapamycin (sirolimus) with off-line and on-line sample pre-concentration techniques and using micellar electrokinetic chromatography (M...
Generalized discoid lupus erythematosus can pose a therapeutic challenge for dermatologists. Current treatment emphasizes photoprotection, topical and systemic steroids, and steroid-sparing immunosupp...
Cirrhosis is often associated with portal hypertension and portal-systemic collateral vessels formation attributed to angiogenesis, which leads to severe complications as hepatic encephalopathy. Sirol...
A plant species of the genus CITRUS, family RUTACEAE that provides the familiar grapefruit. There is evidence that grapefruit juice inhibits CYTOCHROME P-450 isoform 3A4, resulting in delayed metabolism and higher blood levels of a variety of drugs.
A multiprotein complex consisting of MTOR KINASE; MLST8 PROTEIN; rapamycin-insensitive companion of mTOR protein (RICTOR PROTEIN); and PRR5 (proline-rich protein 5). Like MTORC1, it also regulates cell growth and proliferation in response to growth factors but may not be as sensitive to nutrient availability and is insensitive to SIROLIMUS. In contrast to MTORC1, it can regulate the ACTIN CYTOSKELETON through RHO GTPASES to promote the formation of STRESS FIBERS. The mTORC2 complex also plays a critical role in AKT1 PROTEIN KINASE phosphorylation and activation.
A macrolide compound obtained from Streptomyces hygroscopicus that acts by selectively blocking the transcriptional activation of cytokines thereby inhibiting cytokine production. It is bioactive only when bound to IMMUNOPHILINS. Sirolimus is a potent immunosuppressant and possesses both antifungal and antineoplastic properties.
An evolutionarily conserved multiprotein complex that functions as a cellular energy sensor and regulator of protein synthesis for cell growth and proliferation. It consists of TOR SERINE-THREONINE KINASES; REGULATORY-ASSOCIATED PROTEIN OF MTOR (RAPTOR); MLST8 PROTEIN; and AKT1 substrate 1 protein. The activity of the complex is regulated by SIROLIMUS; INSULIN; GROWTH FACTORS; PHOSPHATIDIC ACIDS; some amino acids or amino acid derivatives, and OXIDATIVE STRESS.
A serine threonine kinase that controls a wide range of growth-related cellular processes. The protein is referred to as the target of RAPAMYCIN due to the discovery that TACROLIMUS (commonly known as rapamycin) forms an inhibitory complex with TACROLIMUS BINDING PROTEIN 1A that blocks the action of its enzymatic activity.
