Background: Malaria is a disease causing millions of victims every year and requires new drugs, often due to parasitic strain mutations. Thus, the search for new molecules that possess antimalarial activity is constant and extremely important. However, the potential that an antimalarial drug possesses cannot be ignored, and molecular hybridization is a good strategy to design new chemical entities. Objective: This review artic Read More

Background: Antiplatelet drugs represent the keystone in the treatment and prevention of diseases of ischemic origin, including coronary artery disease. The current palette of drugs represents efficient modalities in most cases, but their effect can be limited in certain situations or associated with specific side effects. In this study, representatives of compounds selected from series having scaffolds with known or potential antip Read More

Objective: A series of novel benzimidazole-incorporated naphthalimide derivatives were designed and prepared in an effort to overcome the increasing antibiotic resistance. Methods: The target novel benzimidazole-incorporated naphthalimide derivatives were synthesized from commercial 4-bromo-1,8-naphthalic anhydride and o-phenylene diamine by aminolysis, Nalkylation and so on. The antimicrobial activity Read More

Background: Many compounds containing a five-membered heterocyclic ring display exceptional chemical properties and versatile biological activities. Objective: The objective of the present study was to prepare the 5-substituted 2-amino-1,3,4- oxadiazole and 2-amino-1,3,4-thiadiazole derivatives and evaluate their potential anticancer, antibacterial and antifungal activities. Methods: Twenty-seven derivatives were synth Read More

Background: Mononcyclic β-lactams are regarded as the most resistant class of β-lactams against a series of β-lactamases, although they possess limited antibacterial activity. Aztreonam, being the first clinically approved monobactam, needs broad-spectrum efficacy through structural modification. Objective: We strive to synthesize a number of monocyclic β-lactams by varying the substituents at N1, C3, and C4 position Read More

Background: Breast cancer is the leading cause of cancer death in women. The current methods of chemotherapy for breast cancer generally have strong adverse reactions and drug resistance. Therefore, the discovery of novel anti-breast cancer lead compounds is urgently needed. Objective: This study aimed to design and synthesize a series of 2-alkyl substituted fluorinated genistein analogues and evaluate their an Read More

Background: Inducible nitric Oxide Synthase (iNOS) plays a key role in the progression of inflammatory diseases by accelerating the production of NO, which makes it an intriguing target to treat inflammation in complex diseases. Therefore, the search is on to develop molecules as selective iNOS inhibitors. Objective: The present work was aimed to design, synthesize and evaluate benzimidazole-coumarin coupled molecules a Read More

Background: Integrase enzyme is a validated drug target to discover novel structures as anti-HIV-1 agents. Objective: This study aimed at developing a novel series of thioimidazolyl diketoacid derivatives characterizing various substituents at N-1 and 2-thio positions of the central ring as HIV-1integrase inhibitors. Methods: In this study, eighteen novel thioimidazolyl DKA derivatives were synthesized in a fivestep parallel Read More
