Aim and Objective: Interleukin-6 has become an attractive protein target. This is found in the progression of colon cancer. It performs various functions in the colon cancer cells such as inflammation, activates various cell types signaling and also promotes proliferation in colon cancer cells. It is a valid target to develop anticolon cancer drug. The purpose of our study is to develop the Three-dimensional Quantitative Structure Read More

Aim and Objective: Caffeic acid (CA) is a cinnamic acid derivative, found in many vegetable products, with powerful antioxidant activity, the ability to increase collagen production and capacity to prevent premature aging of the skin. The classic emulsions of CA are widely used by the consumer to provide a pleasant, refreshing sensorial experience; however, preparations developed in the form of dry film are presented as a tech Read More

Aim and Objective: Vinca domain of tubulin protein is the potential target for different microtubule targeting drugs (MTD). However, its binding mechanism and structure-activityrelationship (SAR) is not well understood in terms of ligand-receptor interactions and structure functionality requirements. This limits the exploitation of vinca domain for developing novel clinical leads. Herein, as a progressive step towards the e Read More

Aim and Objective: According to our interest in developing new methods for the construction of intricate molecules, a reliable polymer-supported (-)-8-phenylmenthyl chiral auxiliary for the addition of different nucleophiles to chiral-supported N-acyliminium precursors were developed. Materials and Methods: Merrifield resin was employed to anchor (-)-8-phenylmenthol, which was prepared by nitration of (-)-8-phenylme Read More

Aim and Objective: Inspired by the impressive biological properties of pyrrolo[2,3- d]pyrimidine units, the objective of this study was to synthesize some new derivatives of heterocyclic compounds with different substituent’s using solvent-free microwave irradiation conditions from readily available starting material. The synthesized compounds were screened for their in vitro anti-microbial, anti-oxidant, anti-cancer activitie Read More

Aim and Objective: Cancer has become one of the leading causes of morbidity and mortality worldwide. Limitations associated with existing agents increase the need to develop more effective anticancer drugs to improve the therapeutic arsenal available. The aim of this study was to synthesize and evaluate the antiproliferative effects of three new thiazacridine derivatives. Material and Methods: Using a three steps synthesis rea Read More

Aim and Objective: MMP-13 belongs to a large family of proteases called matrix metalloproteinases (MMPs) that degrades type II collagen, the main structural protein of articular cartilage. The main pathologic role of MMP-13 over expression is to contribute to the development of osteoarthritis. Methods: To find new inhibitors with possible selectivity for MMP-13 a structure based virtual screening was employed. The inhibitory acti Read More

Aim and objective: This study describes the design and evaluation of an expression vector for Pichia pastoris (pPICZαBHF), which is based on the commercial vector construct pPICZαB. Material and Methods: The performance of pPICZαBHF was evaluated with red fluorescent protein as a reporter. Additional His- and Flag-tags on the N-terminal ensured a simplified protein purification procedure. Transformation efficiency, e Read More

Background: HIV integrase (IN) and reverse transcriptase (RT) are key enzymes for the replication of HIV-1. DNA polymerase and ribonuclease H (RNase H) are the two catalytic domains of HIV-1 RT which are validated as drug targets because of their essence for replication. IN and RNase H domain of RT shares striking structural similarity; it contains conserved DDE triad (two aspartates and one glutamate) and a pair of dival Read More
