Selenium(Se)-containing compounds have attracted a growing interest as anticancer agents over recent decades, with mounting reports demonstrating their high efficacy and selectivity against cancer cells. Typically, Se compounds exert their cytotoxic effects by acting as pro-oxidants that alter cellular redox homeostasis. However, the precise intracellular targets, signalling pathways affected and mechanisms of cell death engaged following treatment vary with the chemical properties of the selenocompound and its metabolites, as well as the cancer model that is used. Naturally occurring organic Se compounds, besides encompassing a significant antitumor activity with an apparent ability to prevent metastasis, also seem to have fewer side effects and less systemic effects as reported for many inorganic Se compounds. On this basis, many novel organoselenium compounds have also been synthesized and examined as potential chemotherapeutic agents. This review aims to summarize the most well studied natural and synthetic organoselenium compounds and provide the most recent developments in our understanding of the molecular mechanisms that underlie their potential anticancer effects.

SLC26A3 (downregulated in adenoma; DRA) is a Cl-/anion exchanger expressed in the luminal membrane of intestinal epithelial cells, where it facilitates electroneutral NaCl absorption. SLC26A3 loss of function in humans or mice causes chloride-losing diarrhea. Here, we identified slc26a3 inhibitors in a screen of 50,000 synthetic small molecules done in Fischer rat thyroid (FRT) cells coexpressing slc26a3 and a genetically encoded halide sensor. Structure-Activity relationship studies were done on the most potent inhibitor classes identified in the screen: 4,8-dimethylcoumarins and acetamide-Thioimidazoles. The dimethylcoumarin DRAinh-A250 fully and reversibly inhibited slc26a3-mediated Cl- exchange with HCO3 -, I-, and thiocyanate (SCN-), with an IC50 of ?0.2 muM. DRAinh-A250 did not inhibit the homologous anion exchangers slc26a4 (pendrin) or slc26a6 (PAT-1), nor did it alter activity of other related proteins or intestinal ion channels. In mice, intraluminal DRAinh-A250 blocked fluid absorption in closed colonic loops but not in jejunal loops, while the NHE3 (SLC9A3) inhibitor tenapanor blocked absorption only in the jejunum. Oral DRAinh-A250 and tenapanor comparably reduced signs of constipation in loperamide-Treated mice, with additive effects found on coadministration. DRAinh-A250 was also effective in loperamidetreated cystic fibrosis mice. These studies support a major role of slc26a3 in colonic fluid absorption and suggest the therapeutic utility of SLC26A3 inhibition in constipation.

Primaquine thiazolidinone derivatives are proposed as promising antimalarial candidates to be tested as primaquine substitutes. Molecular docking and dynamics simulations were applied in the analogues-NQO2 complexes to understand their interactions, and also studied the toxic potential of these derivatives in a set of 16 target proteins. The results of our study suggest that the interactions of five thiazolidinone primaquine derivatives with NQO2 are stronger than the interaction of primaquine and NQO2. The analogue 5n-protein complex seems to be the most stable compared with the primaquine-protein complex. The analogues 5n and 5o are predicted to be in the same class of toxic potential as primaquine. Their interactions with the cytochrome P450 enzymes are also predicted to be weaker, indicating that a better activity/toxicity balance compared with primaquine may be reached.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Electric Literature of 2682-49-7, you can also check out more blogs about2682-49-7

Thiazolidinediones (TZDs) or Glitazones are an important class of insulin sensitizers used in the treatment of Type 2 diabetes mellitus (T2DM). TZDs were reported for their antidiabetic effect through antihyperglycemic, hypoglycemic and hypolipidemic agents. In time, these drugs were known to act by increasing the transactivation activity of Peroxisome Proliferators Activated Receptors (PPARs). The clinically used TZDs that suffered from several serious side effects and hence withdrawn/updated later, were full agonists of PPAR-gamma and potent insulin sensitizers. These drugs were developed at a time when limited data were available on the structure and mechanism of PPARs. In recent years, however, PPAR-alpha/gamma, PPAR-alpha/delta and PPAR-delta/gamma dual agonists, PPAR pan agonists, selective PPAR-gamma modulators and partial agonists have been investigated. In addition to these, several non PPAR protein alternatives of TZDs such as FFAR1 agonism, GPR40 agonism and ALR2, PTP1B and alpha-glucosidase inhibition have been investigated to address the problems associated with the TZDs. Using these rationalized approaches, several investigations have been carried out in recent years to develop newer TZDs devoid of side effects. This report critically reviews TZDs, their history, chemistry, mechanism mediated through PPAR, recent advances and future prospects.

Amines which contain a second functional group in the appropriate position react with carbon monoxide in the presence of selenium to form heterocyclic derivatives in which carbon monoxide is incorporated.For instance, diamines, aminoalcohols, and their related compounds undergo carbonylation to give cyclic ureas, urethanes and the corresponding carbonylated compounds.For diamines and amino alcohols with more than two carbon atoms between the functional groups, intermolecular carbonylative coupling takes place competing with the intramolecular reaction.High selectivity has been attained under specified reaction conditions.Anilines having cyano or acetyl groups on the ortho position afford new classes of selenium-containing heterocycles.In these reactions, carbamoselenoate has been suggested as the common key intermediate.

A new series of benzimidazole bearing pyridine derivatives were synthesized by condensation of 1,2-phenylenediamine with 2-oxo-1,2-dihydro-pyridine-3-carboxylic acid derivative 2 in phosphoric acid to give 3-(1Hbenzo[ d]imidazol-2-yl)-pyridin-2(1H)-one derivative 3. Compound 3 on further reaction with a mixture of phosphorus oxychloride and phosphorus pentachloride gave 2-(2-chloro-) pyridin-3-yl)-1H-benzo[d] imidazole derivative 4. Moreover, 4 were reacted with different amines to give 3-(1H-benzo[d]imidazol-2-yl)-N-(substituted) pyridin-2-amine derivatives 5a-c. Meanwhile, N-(N-(substituted) sulfamoyl) pyridin-3-yl)-1H-benzo[d]imidazole-1-carboxamide derivatives 7a,b were synthesized by reaction of 5c with chlorosulfonyl isocyanate to give 2-(pyridin-3-yl)-1H-benzo [d]imidazole-1-carbonyl) sulfamoyl chloride derivative followed by reaction of the latter with different amines. On the other hand, upon treatment compound 4 with hydrazine hydrate gave the hydrazide derivative 8. The reaction of compound 8 with different alkyl/arylisothiocyanates gave the corresponding thiosemicarbazide derivatives 9a-d, while their cyclo condensation reaction with ethyl chloro acetate gave the corresponding thiazolidin-4-one derivatives 10a-c. Moreover, condensation of 10a,c with aromatic aldehydes afforded the corresponding 5-arylidine-thiazolidin-4-one derivatives 11a,b.

Background: Medicinal interest has focused on beta-carbolines as anticancer agents. Methodology/Results: Several beta-carbolines were designed, synthesized and evaluated for their cytotoxic activity against MCF-7 and A-549 cancer cell lines using MTT assay. Compounds 13a, 13c, 13d and 20a were the most promising showing high selectivity indices. Compounds 13c and 20a showed potent inhibition of topoisomerase (topo-I) and kinesin spindle protein (KSP/Eg5 ATPase) which was confirmed by their docking results into the active site of both enzymes. In silico physicochemical calculations predicted that compounds 13a, 13d and 20a obeyed Lipinski’s rule of five. Conclusion: Compounds 13c and 20a are multitarget anticancer leads that act as potent inhibitors for both topo-I and/or KSP ATPase.
