Genotoxicity and Anticancer Effects of the Aminothiophene Derivatives SB-44, SB- 83, and SB-200 in Cancer Cells.

Introduction: Thiophene derivatives have been widely studied as promising options for the treatment of solid tumors. Previous studies have shown that thiophene derivatives have antileishmanial activity and cytotoxic activity against breast, colon, and ovarian cancer cells.

Methods: In our study, we evaluated the anticancer activities of three aminothiophene derivatives: SB-44, SB-83, and SB-200, in prostate and cervical adenocarcinoma cells.

Synthesis, ADMET Prediction, and Antitumor Profile of Phenoxyhydrazine- 1,3-thiazoles Derivatives.

Background: Cancer is one of the most important barriers to increasing life expectancy in all countries in the 21st century. Investigations of new anti-cancer drugs with low side effects are an urgent demand for medicinal chemists. Considering the known antitumor and immunomodulatory activity of thiazoles, this work presents the synthesis and antineoplastic activity of new thiazoles.

Synthesis, anticancer activity and mechanism of action of new phthalimido-1,3-thiazole derivatives.

In this work, 22 new compounds were obtained and evaluated for their cytotoxic activity on peripheral blood mononuclear cells (PBMC) and eight different tumor cell lines. All compounds displayed IC values above 100 μM when assayed against PBMCs. The cytotoxic assays in tumor cell lines revealed that sub-series of phthalimido-bis-1,3-thiazoles (5a-f) exhibited the best anti-tumor activity profile, presenting viability values below 59 %.

Potential Therapeutic Agents Against Par-4 Target for Cancer Treatment: Where Are We Going?

One of the greatest challenges of cancer therapeutics nowadays is to find selective targets successfully. Prostate apoptosis response-4 (Par-4) is a selective tumor suppressor protein with an interesting therapeutic potential due to its specificity on inducing apoptosis in cancer cells. Par-4 activity and levels can be downregulated in several tumors and cancer cell types, indicating poor prognosis and treatment resistance.

Anticancer properties of thiophene derivatives in breast cancer MCF-7 cells.

Substitutions in thiophene structure give rise to new derivatives with different biological and pharmacological activities. The present study investigated the cytotoxicity activity of some thiophene derivatives in breast cancer cells maintained in two-dimensional (2D) or in three-dimensional (3D) culture and evaluated the anticancer mechanism of these compounds. Cytotoxicity assays were performed against untransformed cells and against breast cancer cell MCF-7.

Decreased serum interleukin 27 in Brazilian systemic lupus erythematosus patients.

The immunological role of interleukin 27 has been reported in various inflammatory diseases, but its importance in systemic lupus erythematosus pathogenesis is not completely established. The aim of this study was to evaluate serum levels of IL-27 in SLE patients and its correlation with clinical manifestations and disease activity. IL-27 levels were assessed in 70 SLE patients and 30 healthy controls by ELISA.
