A promising class of antiprotozoal agents, design and synthesis of novel Pyrimidine-Cinnamoyl hybrids.

Malaria, caused by parasitic protozoans of the Plasmodium genus, continues to be one of the greatest global health crises, especially in Africa. The emergence of antimalarial drug resistance continues to be a health problem necessitating an urgent need for alternative and cost-effective antimalarials. Using a molecular hybridization approach, we report the design and synthesis of an efficacious novel class of antiprotozoal agents; (E)-1-(4-(4,6-diphenylpyrimidin-2-yl)piperazin-1-yl)-3-phenyl prop-2-en-1-one derivatives (8a-r).

Exploring the therapeutic potential of prolinamides as multi-targeted agents for Alzheimer's disease treatment: molecular docking and molecular dynamic simulation studies.

Unlabelled: Alzheimer's disease (AD) presents a significant global health challenge, with its prevalence expected to rise sharply in the coming years. Despite extensive research, effective treatments addressing the multifaceted pathophysiology of AD remain elusive. This study investigates the therapeutic potential of twenty-seven prolinamides (P1 - P27), with the focus on their interactions with key proteins implicated in AD pathogenesis.

Antidiabetes and antioxidant potential of Schiff bases derived from 2-naphthaldehye and substituted aromatic amines: Synthesis, crystal structure, Hirshfeld surface analysis, computational, and studies.

Three Schiff bases were synthesised by the condensation reaction between 2-napthaldehyde and aromatic amines to afford -mesityl-1-(naphthalen-2-yl)methanimine (), ()--(2,6-dimethylphenyl)-1-(naphthalen-2-yl)methanimine () and -(2,6-diisopropylphenyl)-1-(naphthalen-2-yl)methanimine (). The synthesised compounds were characterised using UV-visible, NMR (C & H), and Fourier transform infrared spectroscopic methods while their purity was ascertained by elemental analysis. Structural analysis revealed that the naphthalene ring is almost coplanar with the imine functional group as evident by C1-C10-C11-N1 torsion angles of 176.

Lactate dehydrogenase and malate dehydrogenase: Potential antiparasitic targets for drug development studies.

Parasitic diseases remain a major public health concern for humans, claiming millions of lives annually. Although different treatments are required for these diseases, drug usage is limited due to the development of resistance and toxicity, which necessitate alternative therapies. It has been shown in the literature that parasitic lactate dehydrogenases (LDH) and malate dehydrogenases (MDH) have unique pharmacological selective and specificity properties compared to other isoforms, thus highlighting them as viable therapeutic targets involved in aerobic and anaerobic glycolytic pathways.

Development of niosomes for encapsulating captopril-quercetin prodrug to combat hypertension.

Novel and effective anti-hypertensive agents are required to manage hypertension; therefore, we synthesised a novel antihypertensive drug from captopril and quercetin (cap-que) and explored its antihypertensive potential in a niosomal formulation via molecular hybridisation. The cap-que hybrid was synthesised, and its structure was characterised via NMR, FTIR, and HRMS. Niosomes were then loaded with cap-que using the thin-film hydration method.

Design and synthesis of pyrazolone-based compounds as potent blockers of SARS-CoV-2 viral entry into the host cells.

SARS-CoV-2 are enveloped positive-stranded RNA viruses that replicate in the cytoplasm. It relies on the fusion of their envelope with the host cell membrane to deliver their nucleocapsid into the host cell. The spike glycoprotein (S) mediates virus entry into cells via the human Angiotensin-converting enzyme 2 (hACE2) protein located on many cell types and tissues' outer surface.
