Background: The delaying of absorption of glucose is one of the principal therapeutic approaches of type 2 diabetes. α-glucosidase inhibitors compete with the α-glucosidase enzyme activity, which helps to reduce the conversion of carbohydrates into glucose and thereby control the postprandial hyperglycemia incidence. Objective: The aim of this study was to synthesize a series of novel 1,5-diphenyl pyrrole derivatives and evaluate their in vitro α-glucosidase inhibitory activities. Methods: Compounds were synthesized through a multistep reaction and were evaluated for αglucosidase inhibitory activities. Molecular docking and kinetic studies were carried out to predict the mode of binding and mechanism of inhibition for the most active compounds, 5g and 5b, against α-glucosidase. Results: Synthesized compounds showed good in vitro α-glucosidase inhibitory activity with IC50 values in the range of (117.5 ± 3.8 to 426.0 ± 10.2 μM) as compared to acarbose, the standard drug, (750 ± 8.7 μM). Compound 5g (117.5 ± 3.8 μM) ascertained as the most potent inhibitor of α-glucosidase in a competitive mode. The binding energies of compounds 5g and 5b (119.0 ± 7.5 μM), as observed from the best docking conformations, indicate that they have a lower free binding energy (-3.26 kcal/mol and-3.0 kcal/mol, respectively) than acarbose (2.47 kcal/mol). Conclusion: The results of our study revealed that the synthesized compounds are a potential candidate for α-glucosidase inhibitors for the management of postprandial hyperglycemia for further investigation.

Objective: Several anti-tubulin agents were introduced for the cancer treatment so far. Despite successes in the treatment of cancer, these agents cause toxic side effects, including peripheral neuropathy. Comparing anti-tubulin agents, indibulin seemed to cause minimal peripheral neuropathy, but its poor aqueous solubility and other potential clinical problems have led to its remaining in a preclinical stage. Methods: Herein, indibulin analogues were synthesized and evaluated for their in vitro anti-cancer activity using MTT assay (on the MCF-7, T47-D, MDA-MB231 and NIH-3T3 cell lines), annexin V/PI staining assay, cell cycle analysis, anti-tubulin assay and caspase 3/7 activation assay. Results: One of the compounds, 4a, showed good anti-proliferative activity against MCF-7 cells (IC50: 7.5 μM) and low toxicity on a normal cell line (IC50 > 100μM). All of the tested compounds showed lower cytotoxicity on normal cell line in comparison to reference compound, indibulin. In the annexin V/PI staining assay, induction of apoptosis in the MCF-7 cell line was observed. Cell cycle analysis illustrated an increasing proportion of cells in the sub-G-1 phase, consistent with an increasing proportion of apoptotic cells. No increase in G2/M cells was observed, consistent with the absence of anti-tubulin activity. A caspase 3/7 assay protocol showed that apoptosis induction by more potent compounds was due to activation of caspase 3. Conclusion: newly synthesized compounds exerted acceptable anticancer activity and further investigation of current scaffold would be beneficial.

Background: During recent years, a number of anti-tubulin agents were introduced for treatment of diverse types of cancer. Despite their potential in the treatment of cancer, drug resistance and adverse toxicity, such as peripheral neuropathy, are some of the negative effects of anti-tubulin agents. Among anti-tubulin agents, indibulin was found to cause minimal peripheral neuropathy. Thus far, however, indibulin has not entered clinical usage, caused in part by its poor aqueous solubility and other developmental problems in preclinical evaluation. Objectives: With respect to need for finding potent and safe anticancer agents, in our current research work, we synthesized several indibulin-related diarylpyrrole derivatives and investigated their anti-cancer activity. Methods: Cell cultur studies were perfomred using the MTT cell viability assay on the breast cancer cell lines MCF-7, T47-D, and MDA-MB231 and also NIH-3?T3 cells as representative of a normal cell line. The activity of some of the synthesized compounds for tubulin interaction was studied using colchicine binding and tubulin polymerization assays. The annexin V-FITC/PI method and flow cytometric analysis were used for studying apoptosis induction and cell cycle distribution. Results and conclusion: Two of the synthesized compounds, 4f and 4?g, showed high activity on the MDA-MB231 cell line (IC50?= 11.82 and 13.33?μM, (respectively) and low toxicity on the normal fibroblast cells (IC50?> 100?μM). All of the tested compounds were more potent on T47-D cancer cells and less toxic on NIH-3?T3 normal cells in comparison to reference compound, indibulin. The tubulin polymerization inhibition assay and [3H]colchicine binding assay showed that the main mechanism of cell death by the potent synthesized compounds was not related to an interaction with tubulin. In the annexin V/PI staining assay, the induction of apoptosis in the MCF-7 and MDA-MB231 cell lines was observed. Cell cycle analysis illustrated an increased percentage of sub-G-1 cells in the MDA-MB231 cell line as a further indication of cell death through induction of apoptosis.
