Alteration of the acetylation status of chromatin and other non-histone proteins by HDAC inhibitors has evolved as an excellent epigenetic strategy in treatment of cancers. The present study was sought to identify compounds with positive pharmacological profiles targeting HDAC1. Analogues of Vorinostat synthesized by Cai et al, 2015 formed the test compounds for the present pharmacological evaluation. Hydroxamte analogue 6H showed superior pharmacological profile in comparison to all the compounds in the analogue dataset owing to its better electrostatic interactions and hydrogen bonding patterns. In order to identify compounds with even better high affinity and pharmacological profile than 6H and Vorinostat, virtual screening was performed. A total of 83 compounds similar to Vorinostat and 154 compounds akin to analogue 6H were retrieved. SCHEMBL15675695 (PubCid: 15739209) and AKOS019005527 (PubCid: 80442147) similar to Vorinostat and 6H, were the best docked compounds among the virtually screened compounds. However, in spite of having good affinity, none of the virtually screened compounds had better affinity than that of 6H. In addition SCHEMBL15675695 was predicted to be a carcinogen while AKOS019005527 is Ames toxic. From, our extensive analysis involving binding affinity analysis, ADMET properties predictions and pharmacophoric mappings, we report Vorinostat hydroxamate analogue 6H to be a potential candidate for HDAC inhibition in treatment of cancers through an epigenetic strategy.

Epigallocatechin gallate (EGCG), a well-known antioxidant molecule, has been reported to cause hepatotoxicity when used in excess. However, the mechanism underlying EGCG-induced hepatotoxicity is still unclear. To better understand the mode of action of EGCG-induced hepatotoxicity, we examined the effect of EGCG on human hepatic gene expression in HepG2 cells using microarrays. Analyses of microarray data revealed more than 1300 differentially expressed genes with a variety of biological processes. Upregulated genes showed a primary involvement with protein-related biological processes, such as protein synthesis, protein modification, and protein trafficking, while downregulated genes demonstrated a strong association with lipid transport. Genes involved in cellular stress responses were highly upregulated by EGCG treatment, in particular genes involved in endoplasmic reticulum (ER) stress, such as GADD153, GADD34, and ATF3. In addition, changes in genes responsible for cholesterol synthesis and lipid transport were also observed, which explains the high accumulation of EGCG-induced lipids. We also identified other regulatory genes that might aid in clarifying the molecular mechanism underlying EGCG-induced hepatotoxicity.

Fluoroquinolone (FQ) antibiotics are an important class of synthetic antibacterial agents. These are the most extensively used drugs for treating bacterial infections in the field of both human and veterinary medicine. Herein, the antibacterial and pharmacological properties of four fluoroquinolones: lomefloxacin, norfloxacin, ciprofloxacin, and ofloxacin have been studied. The objective of this study was to analyze the antibacterial characteristics of the different fluoroquinolones. Also, the pharmacological properties of the compounds including the Lipinski rule of five, absorption, distribution, metabolism, and excretion, LD50, drug likeliness, and toxicity were evaluated. We found that among all four FQ molecules, ofloxacin showed the highest antibacterial activity through in silico assays with a strong interaction (-38.52 kJ/mol) with the antibacterial target protein (topoisomerase-II DNA gyrase enzyme). The pharmacological and pharmacokinetic analysis also showed that the compounds ciprofloxacin, ofloxacin, lomefloxacin and norfloxacin have good pharmacological properties. Notably, ofloxacin was found to possess an IGC50 (concentration needed to inhibit 50% growth) value of $0.286{\mu}g/L$ against the Tetrahymena pyriformis protozoa. It also tested negative for the Ames toxicity test, showing its non-carcinogenic character.

Purpose: This study was intended to analyze the types and measurement parameters of non-pharmacological interventional studies for nonalcoholic fatty liver disease (NAFLD). Methods: NAFLD related literatures were systematically reviewed. The existing literatures were searched electronically using the data base of PubMed, a Medline data base of the National Library of Medicine with the key words of nonalcoholic fatty liver disease, NAFLD, nonalcoholic steatohepatitis, and NASH. The criteria for inclusion in this review were 1) non-pharmacological intervention, 2) human, 3) English. Finally, 20 articles were included in the review. Results: The major findings of this study were as follows: 1) the types of non-pharmacological intervention were exercise (35%), caloric restriction (30%), and lifestyle modification with combination both of exercise and caloric restriction (35%), 2) Almost all studies adopted various measurement parameters derived from pathophysiological mechanism-based biomarkers such as anthropometric indices, biochemical parameters, body fat mass, and liver biopsy results. Conclusion: Non-pharmacological interventions have been reported to be effective to improve NAFLD status, and many objective biomarkers confirmed supported these findings. Therefore, the development of nursing interventions for NAFLD subjects is needed and the consideration of using mechanism-based biomarkers is suggested to verify nursing outcomes objectively.

Safety pharmacology studies are conducted to investigated the potential undesirable pharmacodynamic effects of a substance on physiological functions in relation to exposure in the therapeutic range and above. In the International Conference on Harmonisation (ICH), the guideline 'S7A: Safety Pharmacology Studies for Human Pharmaceuticals' has been developed and reached Step 5 of the ICH process in 2001. Now the Korea Food and Drug Administration (KFDA) are going to transfer 'The Guideline for General Pharmacology' into 'The Guideline for Safety Pharmacology'. Safety pharmacology studies should be performed in compliance with Good Laboratory Practice (GLP). Thus, the present paper reviews the Japanese GLP guidelines for pharmaceuticals to help the conduct and inspection of safety pharmacology studies in compliance with GLP. We also reviewed the ICH guidelines 'S7B revised : The Nonclinical Evaluation of the Potential for Delayed Ventricular Repolarization (QT Interval Prolongation) by Human Pharmaceuticals' and 'E14 : The Clinical Evaluation of QT/QTc Interval Prolongation and Proarrhythmic Potential for Non-antiarrhythmic Drugs' to apply our drug approval systems.

A new medical system was started in Korea in 2000 and pharmaceutical affairs law was revised in 2001. According to the revised law, generic substitution is permitted only to therapeutically equivalent generic product. Bioequivalence studies are usually used to demonstrate therapeutic equivalence between reference listed drugs and generic drugs. The issues that are recently heating up in Korea are to increase bioequivalent drug products and at the same time to ensure the credibility of the therapeutic equivalence of generic drugs. Sometimes food can change the bioavailability (BA) of a drug and influence the bioequivalence (BE) between test and reference products as well. Food effects on BA can have clinically significant consequences. Food can alter BA by various means including delaying gastric emptying, stimulating bile flow and changing gastointestinal pH. This paper provides the recently published Korean guideline on food-effect BA and fed BE studies.
