<p class="Abstract">The methanolic extract of <em>Alysicarpus </em>vaginalis was selected for fractionation due to its known reported biological activity. The four fractions were separated and subjected for<em> in vitro</em> antimitotic and anti-proliferative assays along with anti-cancer activity on two human cancers cell lines (SK-MEL-2 and Hep-G2). The antimicrobial potential of fractions had been evaluated against bacteria and fungi. From all fractions, acetone and n-butanol fractions were effective against the cell lines. They show strong inhibitory action with mitotic index 6.2 and 8.4 mg/mL and IC<sub>50 </sub>values of anti-proliferative assay in between 19.7 to 14.2 mg/mL respectively, which was found to be comparable to the standard methothrexate 5.9 mg/mL and 13.2 mg/mL respectively. In antimicrobial activity, the zone of inhibition had been observed in the range of 12-27 mm and MIC value was found in the range of 0.2-0.1 mg/mL. The acetone fraction was found to be most active against fungi, and<em> E. coli</em> whereas chloroform and n-butanol fractions were more effective against <em>S. aureus</em> and <em>B. </em>subtilis. The phytochemical characterization by HPLC analysis indicated the presence of important polyphenolic and steroidal compounds.</p>

With the purpose of discovering new anticancer molecules that might have fewer side effects or reduce resistance to current antitumor drugs, a bioprospecting study of the microalgae of the Cuatro Cienegas Basin (CCB), an oasis in the Chihuahuan desert in Mexico was conducted. A microalgae was identified as Granulocystopsis sp. through sequencing the rbcL gene and reconstruction of a phylogenetic tree, and its anticancer activities were assessed using various in vitro assays and different cell lines of human cancers, including lung, skin melanoma, colorectal, breast and prostatic cancers, as well as a normal cell line. The values of IC50 of the microalgae methanolic extract using the MTT assay were lower than 20 μg/ml, except that in the lung cancer line and the normal cell line. In vitro, the microalgae extract caused the loss of membrane integrity, monitored by the trypan blue exclusion test and exhibited marked inhibition of adhesion and cell proliferation in cancer cell lines, through the evaluation of the clonogenic assay. Also, typical nuclear changes of apoptotic processes were observed under the microscope, using the dual acridine orange/ethidium bromide fluorescent staining. Finally, the microalgae extract increased the activity of caspases 3 and 7 in skin melanoma, colon, breast and prostate cancer cells, in the same way as the apoptotic inductor and powerful antitumoral drug, doxorubicin. This study shows the anticancer activity from Granulocystopsis sp., a microalgae isolated from the CCB.

In the present study, eight numbers of new 3- (4-methoxy phenyl)-5-substituted phenyl-2-pyrazoline-1-carbothioamide (5a-h) have been synthesized from 1- (4-methoxy phenyl)-3- (substituted phenyl)-prop-2-en-1-one (3a-h) and structurally characterized by using FT-IR, 1H NMR, 13C NMR, Mass and Elemental analysis. The synthesized molecules were biologically evaluated for their in vitro anticancer activity against human breast adenocarcinoma (MCF-7), liver cancer (Hep-G2) and leukaemia cancer (K-562) cell line using Sulforhodamine B (SRB) bioassay technique. From the all synthesized compounds 5a, 5c, 5d, and 5e exhibited potent anticancer activity (GI50= <10µg/ml) as compared to the controlled drug 5-Fluorouracil (5-FU) (GI50=44.5µg/ml) and Adriamycin (ADR) (GI50= <10µg/ml) on MCF-7 cell lines. Besides this, all the synthesized compounds have exhibited moderate activity against human liver cancer (Hep-G2) and leukaemia cancer (K-562) cell lines. In addition, molecular docking studies were also explored in order to study the probable binding specificity into the active site of Epidermal Growth Factor Receptor tyrosine kinase (EGFR) (PDB ID: 1M17) using Molegro Virtual Docker Evaluation 2013 6.0.1 (MVD). Based on the molecular docking result, it was found that compound 5a exhibited the best interaction with the above target (i.e., EGFR) by interacting with specific amino acid residues such as: Thr 766, Gin 767, Thr 830, Cys 575, Ala 719 and Met 769.

Background: Thiophene ring forms important building block in medicinal chemistry. Literature reveals that thiophene ring in combination with different groups shows different activity. By keeping these things in mind we have designed and synthesized a new series of amide and sulfonamide coupled thiophene. A series of novel substituted 3-sulfamoylbenzo[b]thiophene-4- carboxamide molecules containing sulfonamide and amide group were designed, synthesized and used for anti-proliferative activity study. Methods: The final compounds 16-36 were synthesized by using series of reactions comprising sulfonation, sulfonamide coupling, hydrolysis and peptide coupling. The yields of compounds 16- 36 are in the range of 90-98%. The structures of the synthesized compounds were elucidated and confirmed by 1H NMR, 13C NMR, LCMS and the purity was checked through HPLC analysis. The compounds were further tested for their in vitro anticancer activity against a series of cell lines A549, HeLa, MCF-7 and Du-145. Results: The intermediates 8-13, 15 and final compounds 16-36 were synthesized in good yields. The synthesized compounds were further tested for their anticancer activity and most of compounds showed moderate to good anticancer activity against all four cell lines. Conclusion: We have synthesized 21 compounds and were screened for anticancer activity against MCF-7, HeLa, A-549 and Du-145 cancer cell lines. Most of the compounds were active for tested cell lines with IC50 value in the range of 1.81 to 9.73 μM. The compounds 18, 19, 21, 25, 30, 31 and 33 are most active in cell line data with IC50 value in the range of 1.81 to 2.52 μM.

Background: Sepsis is a life-threatening condition often associated with a high incidence of multiple organs injury. Several papers suggested the immune response by itself, with the production of humoral inflammatory mediators, is crucial in determining organ injury. However, little is known of how sepsis directly induces organ injury at the cellular levels. To assess this point, we set up an in vitro study to investigate the response of renal tubular cells (RTCs), monocytes (U937) and hepatocytes (HepG2) after 24 h-incubation with septic patients’ plasma. Methods: We enrolled 26 septic patients (“test” group). We evaluated cell viability, apoptosis and necrosis by flow cytometer. Caspase-3,-8,-9 and cytochrome-c concentrations have been analyzed using the Human enzyme-linked immunosorbent assay kit. Results: We found that a decrease of cell viability in all cell lines tested was associated to the increase of apoptosis in RTCs and U937 (p < 0.0001) and increase of necrosis in HepG2 (p < 0.5). The increase of apoptosis in RTCs and U937 cells was confirmed by higher levels of caspase-3 (p < 0.0001). We showed that apoptosis in both RTCs and U937 was triggered by the activation of the intrinsic pathway, as caspase-9 and cytochrome-c levels significantly increased (p < 0.0001), while caspase-8 did not change. This assumption was strengthened by the significant correlation of caspase-9 with both cytochrome-c (r = 0.73 for RTCs and r = 0.69 for U937) and caspase-3 (r = 0.69 for RTCs and r = 0.63 for U937). Conclusion: Humoral mediators in septic patients’ plasma induce apoptosis. This fact suggests that apoptosis inhibitors should be investigated as future strategy to reduce sepsis-induced organ damages.
