Background: Schizophrenia is a disorder with complex etiology with hyperdopaminergia as the leading underlying cause. Atypical antipsychotics are the agents which do not give rise to significant extrapyramidal side effects and are more effective against negative symptoms of schizophrenia. Introduction: A new series of chloro-substituted substituted aryloxypiperazine derivatives and their indole based derivatives was designe Read More

Background: Chalcones, originated from natural product, have been broadly studied their biological activity against various proteins which at the molecular level, are responsible for the progress of the diseases in cancer (e.g. kinases), inflammation (oxidoreductases), atherosclerosis (cathepsins receptor), and diabetes (e.g. α-glucosidase). Objective: Here we synthesize 10 chalcone derivatives to be evaluated their in Read More

Background: Quinazolines and quinazolinones constitute a major class of biologically active molecules, both from natural and synthetic sources. The quinazolinone moiety is an important pharmacophore showing many types of pharmacological activities as shown in recent exhaustive review on the chemistry of 2-heteroaryl & heteroalkyl-4-quinazolinones4-quinazolinones that are the formal condensation products of anthranilic a Read More

Background: The frequent use of antibacterial agents leads to antimicrobial resistance, which is one of the biggest threats to global health today. Therefore, the discovery of novel antimicrobial agents is still urgently needed to overcome the severe infections caused by these putative pathogens resistant to currently available drugs. Objective: The present work was aimed to synthesize and investigate the preliminary st Read More

Background: Antimicrobial resistance is a persistent problem regarding infection treatment and calls for developing new antimicrobial agents. Inhibition of bacterial β-ketoacyl acyl carrier protein synthase III (FabH), which catalyzes the condensation reaction between a CoAattached acetyl group and an ACP-attached malonyl group in bacteria is an interesting strategy to find new antibacterial agents. Objective: The aim of t Read More

Background: For more than 60 years, the lack of new anti-tuberculosis drugs and the increase of resistant Mycobacterium tuberculosis lineages exhibit a therapeutic challenge, demanding new options for the treatment of resistant tuberculosis. Objective: Herein, we determined the (i) activities of (-)-camphene and its derivatives and (ii) combinatory effect with pyrazinamide (PZA) against Mycobacterium tuberculosis in Read More

Background: FufangKushen injection’ was a Chinese Traditional anticancer drug, which has been widely used to treat cancer in combination with other anticancer drugs. Objective: Our goal is to synthesize a series of novel 13-dithiocarbamates matrine derivatives using matrine (1) as the lead compound, and evaluate the biological activities of the obtained compounds. Methods: The in vitro cytotoxicity of the target compounds Read More

Background: Azolopyrimidines are imposed on the arena of drugs treated for cancer. The urgent need to discover new selective anticancer agents, paved the way to explore the antitumor significance of such fused systems. From the synthetic point of view, Microwave facilitated technique for synthesis is very strongly associated with green method in chemistry field. Aim: Our aim is to synthesize bioactive compounds using doc Read More

Background: In order to make some progress in discovering the more effective way to eliminate ROS which cause the oxidative stress in organism in humans and bearing in mind the fact that ethyl-2-hydroxy-4-aryl(alkyl)-4-oxo-2-butenoates (β-diketonates) belong to a class of biologically active compounds, series of β-diketonates were synthesized, characterized, and tested to evaluate there antioxidant activity. Further, to investi Read More

Background: Stilbene phytalexis (1,2-diphenyloethylen) and benzamide are beneficial for human health. To increase the stilbene ring activity, a new series of its derivatives containing benzamide structure was synthesized and evaluated for their in vitro antioxidant power. Methods: 1H nuclear magnetic resonance, mass spectroscopy, and chromatographic analyses were used to confirm the successful synthesis. The antioxidant Read More

Background: The delaying of absorption of glucose is one of the principal therapeutic approaches of type 2 diabetes. α-glucosidase inhibitors compete with the α-glucosidase enzyme activity, which helps to reduce the conversion of carbohydrates into glucose and thereby control the postprandial hyperglycemia incidence. Objective: The aim of this study was to synthesize a series of novel 1,5-diphenyl pyrrole derivativ Read More

In the following article, the author reported an error in the abstract’s result section [1]. The results section of the abstract has been changed as follows: Results: The main benefits (e.g., specialized centres for the treatment of CF exist or a new breakthrough in the gene therapy of CF has been made) and limitations (e.g., comorbidity of CF, lifelong and costly treatment, or adverse impact on patient’s and caregiver’s quality Read More
