Cancer is a condition in which body cells grow uncontrollably and spread to other parts of the body or grow at a particular location. Depending on their location, cancer is named or categorized. Breast cancer is the second most constantly determined and one of the prime reasons for cancer death among females. Many external factors like carcinogenic agents and internal factors like genetic factors are responsible for causin Read More

The dosing pattern of the conventional drug delivery system results in continuously changing and unpredictable plasma concentrations as this system has modest control on the release of the drug along with almost negligible effectual concentration near the site of interest. The problems coupled with conventional drug delivery can be triumphed over by employing osmotic drug delivery systems, which are one of the most Read More

Aims: The synthesis of bioactive compounds has antioxidant potential. Background: All aerobic bodies including human beings, have antioxidant defense systems that protect them from oxidative damage, and many enzymes to remove or heal damaged molecules. However, this normal antioxidant mechanism can be incompetent, and hence dietary intakes of antioxidant compounds are important. Objective: This study ai Read More

Background: Heterocyclic compounds are vital for research due to their diverse pharmacological profiles. They are key structural components of many of the potent antimicrobial drugs available on the market today but still facing the problem of drug resistance by microbes. Indole and its derivatives display versatile pharmacological activities, such as analgesic, antimicrobial, antidepressant, antidiabetic, anti-convulsant, an Read More

Introduction: The Diphtheria vaccine is currently manufactured by chemical inactivation of Diphtheria toxin (DT) following large-scale cultivation of the pathogenic Corynebacterium diphtheriae. The development of non-toxic variants of DT in non-pathogenic recombinant hosts improves the process safety aspects considerably and is therefore desirable. The cytotoxicity of DT was exerted through ADPribosylation of elongatio Read More

Background: Alzheimer's disease (AD) is the most common brain disorder and remains a major health concern worldwide. Considering the highly complex mechanisms of AD, the search for agents based on a multitarget-directed ligands (MTDLs) strategy to treat AD may be more promising than the traditional “one drug-one target” strategy. Inhibition of Poly (ADP-ribose) polymerases-1 (PARP-1) has a potentially therapeutica Read More

Objective: The study aims to explore the mechanism of Qingchang Suppository in the treatment of ulcerative colitis from the perspective of network pharmacology. Methods: The TCM Pharmacology database and analysis platform (TCMSP) were used to determine the effective components and related target information of the Qingchang Suppository. The main objective is to search the target genes related to ul Read More

Background: Studies have shown that epigallocatechin-3-gallate (EGCG), which is present in green tea at a higher rate than other components, has an additive or synergistic cytotoxic effect when applied with different anticancer drugs and reduces the side effects caused by anticancer drugs. It is known that the order of administration of drugs in combined applications also affects cytotoxicity. In this context, our study determine Read More

Background: Nepeta binaludensis Jamzad is a perennial medicinal plant with various pharmacological effects. However, the neuroprotective effects of Nepeta binaludensis extracts have not yet been investigated. This study aimed to examine the effects of N. binaludensis hydro-alcoholic extract (NBE) on oxidative stress markers and apoptosis-related proteins in PC12 cells exposed to oxygen-glucose deprivation/ reperfusion (OGD Read More

Background: HSP90, a critical molecular chaperone, has become a promising molecular target to be involved in multiple signaling pathways of tumor progression and metastasis. Objective: This study intends to find a novel phytolead targeting HSP90. Methods: In this scenario, we employed an in silico combinatorial approach incorporating 3D-QSAR, pharmacophore generation, pharmacokinetics, docking, MD simulation and Read More

Background: Benzoylureas are the most commonly used chitin synthesis inhibitors. But, the exact target site of benzoylurea insecticides has not been identified. Objective: To study whether benzoylphenylureas analogues with a bipartite model could be designed and synthesized as novel insecticides with improved activities. Methods: Based on the bipartite model of the sulfonylurea receptor binding site and commercial dif Read More
