Series of novel substituted Synthesis of N-{[5-(substituted)-1,3,4-oxadiazole-2-yl] carbamothioyl} derivatives containing 1,3,4-oxadiazole moiety were synthesized by microwave as a green chemistry method and conventional method by using pyridine 3- carboxylic acid as a starting material. The structures of the synthesized compounds were characterized by physicochemical data, IR, Mass spectra and 1HNMR. All the newly synthesized compound screened for their antimicrobial and In-vivo and In-vitro Anti-inflammatory studies. Anti-inflammatory studies revealed that compound 4f showed significant in-vivo and in-vitro anti-inflammatory activity as well potent antimicrobial activity.

AbstractA series of novel 1,3,4-thiadiazole derivatives bearing an amide moiety were designed, synthesized, and evaluated for their in vitro antitumor activities against HL-60, SKOV-3 and MOLT-4 human tumor cell lines by MTT assay. Ethyl 2-((5-(4-methoxybenzamido)-1,3,4-thiadiazol-2-yl)thio)acetate (5f) showed the best inhibitory effect against SKOV-3 cells, with an IC50 value of 19.5 μm. In addition, the acridine orange/ethidium bromide staining assay in SKOV-3 cells suggested that the cytotoxic activity of 5f occurs via apoptosis.

Leishmaniasis is a neglected disease that affects 12 million people living mainly in developing countries. Herein, 24 new N-oxide-containing compounds were synthesized followed by in vitro and in vivo evaluation of their antileishmanial activity. Compound 4f, a furoxan derivative, was particularly remarkable in this regard, with EC50 value of 3.6 μM against L. infantum amastigote forms and CC50 value superior to 500 μM against murine peritoneal macrophages. In vitro studies suggested that 4f may act by a dual effect, by releasing nitric oxide after biotransformation and by inhibiting cysteine protease CPB (IC50: 4.5 μM). In vivo studies using an acute model of infection showed that compound 4f at 7.7 mg/Kg reduced ~90% of parasite burden in the liver and spleen of L. infantum-infected BALB/c mice. Altogether, these outcomes highlight furoxan 4f as a promising compound for further evaluation as an antileishmanial agent.

Synthesis And Biological Evaluation

To develop a safer immunosuppressant for organ transplantation and autoimmune disease treatment, in this study, several of novel amino alcohol derivatives containing thioether moiety were synthesized with 7-bromo-tetralin-2-one as starting material, and Suzuki coupling reaction and Bucherer-Bergs reaction as key steps. Their activity as sphingosine 1-phosphate receptor type 1 (S1P1) agonists were evaluated by [γ-35S] GTP binding assay. Among the thioether substituted compounds, compound 10 showed good activity as S1P1 agonist at low micromolar concentration (EC50 = 0.698 μmol/L). The result suggested that it has potential activity against autoimmune diseases and immunosuppressant of organ transplantations.

A series of (1,3-diphenyl-1H-pyrazol-4-yl) methyl benzoate derivatives (6a–10d) were designed and synthesized and evaluated as BRAFV600 inhibitors. Among them, compound 10a showed the most potent inhibitory activity against A375, WM266.4 and BRAFV600Ein vitro with IC50 values of 1.36 μM, 0.94 μM and 0.11 μM, respectively.
