Background: Acanthamoeba is an opportunistic pathogen widely spread in the environment. Acanthamoeba causes excruciating keratitis which can lead to blindness. The lack of effective drugs and its ability to form highly resistant cyst are one of the foremost limitations against successful prognosis. Current treatment involves mixture of drugs at high doses but still recurrence of infection can occur due to ineffectiveness of Read More

Background: Reversed-phase liquid chromatography may cause difficulties, especially in the case of basic drugs due to the strong silanophilic interactions in the partition mechanism. Recently, imidazolium-based ionic liquids additives appeared interesting and a convenient solution for suppressing the harmful effect of free residuals of silanol groups, allowing remodeling of the stationary/mobile-phase system, and thus i Read More

Background: 3-Phosphoinositide Dependent Protein Kinase-1 (PDK1) is being lately considered as an attractive and forthcoming anticancer target. A Protein Data Bank (PDB) cocrystallized crystal provides not only rigid theoretical data but also a realistic molecular recognition data that can be explored and used to discover new hits. Objective: This incited us to investigate the co-crystallized ligands' contacts inside the PDK1 bind Read More

Background: Chalcones substituted by methoxyl groups have presented a broad spectrum of bioactivities, including antifungal, antibacterial and antiproliferative effects. However, a clear and unambiguous investigation about the relevance of this substituent on the chalcone framework has not been described. Objective: The purpose of this work is to assess the antibacterial, antifungal and antiproliferative activities of the tw Read More

Background: Melanogenesis is a process of melanin synthesis, which is a primary response for the pigmentation of human skin. Tyrosinase is a key enzyme, which catalyzes a ratelimiting step of the melanin formation. Natural products have shown potent inhibitors, but some of these possess toxicity. Numerous synthetic inhibitors have been developed in recent years may lead to the potent anti– tyrosinase agents. Objective: A Read More

Background: Acetylcholinesterase (AChE), a serine hydrolase, is an important drug target in the treatment of Alzheimer's disease (AD). Thus, novel AChE inhibitors were designed and developed as potential drug candidates, for significant therapy of AD. Objective: In this work, molecular modeling studies, including CoMFA, CoMFA-RF, CoMSIA, HQSAR and molecular docking and molecular dynamics simulations were perfor Read More

Background: Malaria is a growing infectious disease burden due to the increasing emergence of resistant strains of Plasmodium falciparum. Because of the limited therapeutic efficacy of available antimalarial drugs, the development of potent antimalarial drug agents is therefore an urgent requirement to fight against resistant malaria. Objective: The objective of this work was to develop novel quinoline-baed antimal Read More

Introduction: Integrase is a validated drug target for anti-HIV-1 therapy. The second generation integrase inhibitors display π-stacking interaction ability with 3’-end nucleotide as a streamlined metal chelating pharmacophore. Methods: In this study, we introduced benzoxazin-3-one scaffold for integrase inhibitory potential as bioisostere replacement strategy of 2-benzoxazolinone. Results: Molecular modeling studies revealed th Read More

Background: Alzheimer’s disease (AD) is progressive and irreversible neurodegenerative disorder. Current pharmacotherapy is not able to stop progression of the disease and can only improve cognitive functions. Therefore, new drugs are being sought that will slow down the development of the disease. Objective: Novel phosphorus and thiophosphorus tacrine derivatives 7-14 were designed, synthesized and their biological ac Read More

Background: The development of novel antineoplastic agents remains highly desirable. Objective: This study focuses on the design, synthesis, and antitumor evaluation of phenyl ureas bearing 5-fluoroindolin-2-one moiety. Methods: Three sets of phenylureas were designed and synthesized and their antiproliferative ability was measured against four human carcinoma cell lines (Hela, Eca-109, A549, and MCF-7) via MTT assay. In Read More

Background: NEDD8 activating enzyme (NAE) plays a critical role in various cellular functions in carcinomas. The selective inhibition of NAE could mediate the rate of ubiquitination and the subsequent degradation of proteins associated with cancer so as to achieve the purpose of treatment. Objective: In this article, we decided to study the synthesis and screening of 4-amino substituted 2H-chromen-2-one derivatives against Read More

Background: One of the possible ways of improving the activity and selectivity profile of anticancer agents is to design drug carrier systems employing nanomolecules. Calix[4]arene derivatives and chlorambucil and ibuprofen are important compounds that exhibit interesting anticancer properties. Objective: The objective of this article is the synthesis of new calix[4]arene-derivative conjugates of chlorambucil or ibuprofe Read More

Background: The antioxidant, anticarcinogenic, and antimicrobial activities of Verbascum Thapsus L., known as great mullein, (an important medicinal plant containing different biochemical compounds including sesquiterpenes, flavonoids, saponins and lignins) were determined. There is not much data, to our knowledge, in this respect. Methods: The antioxidant activities of V. Thapsus were investigated by the DPPH (2, 2- Read More

Background: This research project is designed to identify the anti-diabetic effects of the newly synthesized compounds to conclude the perspective of consuming one or more of these new synthetic compounds for diabetes management. Introduction: A series of dihydropyrimidine (DHPM) derivative bearing electron releasing and electron-withdrawing substituent’s on phenyl ring (a-j) were synthesized and screened for anti Read More
