Background: A novel copper-catalyzed synthesis of substituted-1,2,3-triazole derivatives has been developed and performed by Huisgen 1,3-dipolar cycloaddition reaction of azides with alkynes. The reaction is one-pot multicomponent. Objective: We state the advancement and execution of a methodology allowing for the synthesis of some new substituted 1,2,3-triazole analogues with antimicrobial activity. Methods: A series of Read More

Background: B-cell Lymphoma Extra Large (Bcl-XL) belongs to B-cell Lymphoma two (Bcl-2) family. Due to its over-expression and anti-apoptotic role in many cancers, it has been proven to be a more biologically relevant therapeutic target in anti-cancer therapy. In this study, a Quantitative Structure Activity Relationship (QSAR) modeling was performed to establish the link between structural properties and inhibitory potency Read More

Background: Apart from the “hit drugs”, there are many others being studied for their potent activity against several hostilities. To date, anticancer research has been exploited on the inherent versatility and active core skeleton of the compounds. Literature suggests that nitrogen rich molecules are most active and found in their potent cancer activity. Purine-based compounds such as olomoucine and roscovitine, which contain ot Read More

Background: A series of novel 2,6-dichloro-4-(trifluoromethyl)phenyl)-3-(difluoromethyl)- 1H-pyrazole-4-carboxamide derivatives were designed and synthesized. Methods: All the title compounds were confirmed by 1H NMR and MS. Results and Conclusion: The primarily nematicidal activity results indicated that some of them exhibited moderate control efficacy against the tomato root-knot nematode disease caused by Meloidogyne incognita.

Background: A series of novel cinnamic acid piperazine amide derivatives has been designed and synthesized, and their biological activities were also evaluated as potential tyrosinase inhibitors. Methods: Compounds 9, 11 and 17 showed the most potent biological activity (IC50 = 66.5, 61.1 and 66 μM, respectively). In silico docking simulation was performed to position compound 11 into the Agaricus bisporus mushroom tyro Read More

Background: In this study, nine novel compounds, bearing N-[2-(4-substituted piperazine-1-yl)acetyl]-N'-[bis-(4-fluorophenyl)methyl]piperazine structures were synthesized. Methods: Their cytotoxic properties were evaluated in vitro by NCI-60 Sulforhodamine B (SRB) assay against human cancer cell lines: Huh7 (hepatocellular), MCF7 (breast) and HCT116 (colorectal). Results and Conclusion: According to the activity data, Read More

Background: Recently, we reported synthesis and neuroprotective activity of some new 1,2,4-triazine derivatives against H2O2 and β-amyloid toxicity in two neurotic cell lines, SHSY5Y and PC12. Methods: The promising results obtained prompted us to further study on these potent neuroprotective agents. In the current study, in vivo anti-inflammatory effect and also genoprotective activity of these compounds in en Read More

Background: In the present study, the formation of 2, 4, 4-trimethyl-7,2'4'-trihydroxy flavan has been used as the key feature for the formation of new 1,3-benzoxazines. This reaction was carried out via Mannich-condensation reaction, the 7-hydroxy group of flavan was reacted with different primary amines in the presence of formaldehyde. Methods: All the synthesized compounds were characterized on the basis of FT-IR, NM Read More

Background: In view of the estrogenic receptor inhibitory properties of coumarin nucleus, long chain nature of fatty acid and anti-breast cancer activity of fatty acids, it was proposed to attach long chain fatty acids at 3rd,4th and 7th position of coumarin nucleus and evaluate for their anti-breast cancer activity through suitable in-vitro methods. Methods: The present study focuses a library of fatty acid coumarin conjugates Read More

Background: Azoles are commonly used in the treatment and prevention of fungal infections. They suppress fungal growth by acting on the heme group of lanosterol 14α-demethylase enzyme (CYP51), thus blocking the biosynthesis of ergosterol. Objectives: Due to the importance of pyrazolines in the field of antifungal drug design, we aimed to design and synthesize new pyrazoline-based anticandidal agents. Methods Read More

Background: A series of chalcones and flavones were synthesized from 2'-hydroxyacetophenone and substituted aromatic aldehydes via Simmons-Schmidt condensation followed by oxidative cyclization. Methods: Characterization of the obtained structures was established on the basis of their spectroscopic data. The synthesized compounds were screened for their antimicrobial activities against five bacterial strains (Citrobacte Read More
