Pharmacokinetics of Midazolam in preterm neonates with an insight in brain Tissue: A PBPK approach.

Physiological maturity is a gradual process taking place throughout infancy and childhood. Though for years anatomical growth has been the basis for dose calculation in pediatric population, physiological immaturity can-not be overlooked especially in neonates. The potential difference in physiology can significantly affect the outcomes of treatment and may result in under dosing or over-dosage.

Anticancer effect of Indanone-based thiazolyl hydrazone derivative on p53 mutant colorectal cancer cell lines: An and study.

Colorectal cancer is a major health problem, and it is the third most diagnosed cancer in the United States. The current treatment for colorectal cancer includes irinotecan, a topoisomerase I inhibitor, and other targeted drugs, such as bevacizumab and regorafenib. The low response rates and incidence of high toxicity caused by these drugs instigated an evaluation of the anticancer efficacy of a series of 13 thiazolyl hydrazone derivatives of 1-indanone, and four compounds among them show favorable anticancer activity against some of the tested colorectal cancer cell lines with IC values ranging from 0.

WB-PBPK approach in predicting zidovudine pharmacokinetics in preterm neonates.

Antiretroviral therapy has been the mainstay of treatment for neonates born to HIV infected mothers. Neonates born prematurely to HIV positive mothers are underdeveloped not only in anatomical terms but also in their physiological systems. Zidovudine, the first antiretroviral drug in clinical therapy for the treatment of HIV has been approved for use in preterm neonates both prophylactically and therapeutically.

Enzyme and Transporter Kinetics for CPT-11 (Irinotecan) and SN-38: An Insight on Tumor Tissue Compartment Pharmacokinetics Using PBPK.

Background: Computational tools are becoming more and more powerful and comprehensive as compared to past decades in facilitating pharmaceutical, pharmacological and clinical practice. Anticancer agents are used either as monotherapy or in combination therapy to treat malignant conditions of the body. A single antineoplastic agent may be used in different types of malignancies at different doses according to the stage of the disease.

Physiologically based pharmacokinetic modeling for predicting irinotecan exposure in human body.

Colorectal cancer is the third leading cause of cancer-related deaths in the United States. Treatment of colorectal cancer remains a challenge to clinicians as well as drug developers. Irinotecan, a Camptothecin derivative, is successfully used for the treatment of this rapidly progressing malignancy and finds its place in the first line of therapeutic agents.

Prediction of Clearance in Neonates and Infants (≤ 3 Months of Age) for Drugs That Are Glucuronidated: A Comparative Study Between Allometric Scaling and Physiologically Based Pharmacokinetic Modeling.

The objective of this study was to evaluate the predictive performances of allometric models and a physiologically based pharmacokinetic model (PBPK) to predict clearance of glucuronidated drugs in neonates (≤ 3 months of age). From the literature, clearance values for 9 drugs (glucuronidated) for neonates and adults were obtained. Three allometric models were used to predict clearances of these glucuronidated drugs.

Prediction of Clearance and Dose of Midazolam in Preterm and Term Neonates: A Comparative Study Between Allometric Scaling and Physiologically Based Pharmacokinetic Modeling.

Children are not small adults because besides size there are subtle physiological and biochemical differences between children and adults. Like adults, children also require medicine for the management or cure for the underlying diseases. To select a right dose in children, pharmacokinetic (PK) information is warranted.

Analyses of bile from gallbladders of Arius platystomus, Arius tenuispinis, Pomadasys commersonni and Kishinoella tonggol.

Bile from gallbladders of Arius platystomus (Singhara), Arius tenuispinis (Khagga), Pomadasys commersonni (Holoola) and Kishinoella tonggol (Dawan) were derivatised and analysed by GC-MS for identification of bile acids and bile alcohols. Cholic acid and Chenodeoxycholic acid were found as major bile acids in Arius platystomus, Arius tenuispinis and Pomadasys commersonni. Other bile acids identified in Arius platystomus were allochenodeoxycholic acid, allodeoxycholic acid, 3α,7α,12α-trihydroxy-24-methyl-5β-cholestane-26-oic acid, and 3α,7α,12α, 24-tetrahydroxy-5α-cholestane-26-oic acid.

Antineoplastic activity of Holoptelea integrifolia (Roxb.) Planch bark extracts (in vitro).

Cancer remains the major public health concern with a number of cancer patients relying on chemotherapy as a treatment option. Although, advances in biomedical research have led to increased anticancer agents in recent years, the treatment is not always effective due to resistance, toxicity or other factors. Phytochemicals and their active components isolated from plants have provided diversified effective drugs many of them are currently used against cancer and other diseases.
