Organic Phosphorus Compounds. 5. (4-Benzothiazol-2-ylbenzyl)amidophosphonate as Potent Calcium Antagonistic Vasodilators

Structural modification of the calcium antagonist fostedil (KB-944) and their coronary vasodilator activity are described.Amidophosphonate 4a-m, lactam amidophosphonate 7a-l, and diamide dilactam 10 were prepared, and their coronary vasodilator activity was assessed in dogs.Many compounds exhibited coronary vasodilator activity superior to that of fostedil.Among them, the 2-oxopyrrolidine derivative 7a was the most effective compound.Its action as a coronary vasodilator was 3 and 2 times more potent than that of fostedil and diltiazem hydrochloride, respectively.

Glucosinolate hydrolysis products in the crucifer Barbarea vulgaris include a thiazolidine-2-one from a specific phenolic isomer as well as oxazolidine-2-thiones

Two isomeric phenolic glucosinolates, m- and p-hydroxyl derivatives of epiglucobarbarin [(R)-2-hydroxy-2-phenylethylglucosinolate], co-occur in an eastern chemotype (P-type) of the crucifer Barbarea vulgaris along with epiglucobarbarin itself. Levels of the phenolic derivatives in B. vulgaris were low in summer but higher during fall and winter, allowing isolation of all three glucosinolates. Hydrolysis in vitro, catalyzed by Sinapis alba myrosinase at near neutral pH, resulted in expectable oxazolidine-2-thione type hydrolysis products of epiglucobarbarin and its m-hydroxyl derivative. In contrast, a thiazolidine-2-one type product was formed in vitro from p-hydroxy epiglucobarbarin and characterized by UV, IR, MS/MS and 2D NMR. Maceration of leaf material resulted in disappearance of the glucosinolates and formation of the same oxazolidine-2-thione and thiazolidine-2-one products as found in vitro. The detected amounts were comparable to initial amounts of precursor glucosinolates. The corresponding oxazolidine-2-thione type product was also detected quantitatively from glucobarbarin in foliage of a western genotype (G-type). We suggest that p-hydroxy epiglucobarbarin is initially converted into the conventional oxazolidine-2-thione, which would further rearrange to a thiazolidine-2-one due to the activating effect of the p-hydroxyl group. We conclude that a subtle difference between isomeric phenolic glucosinolates results in significantly different natural hydrolysis products.

From fighting depression to conquering tumors: A novel tricyclic thiazepine compound as a tubulin polymerization inhibitor

A novel tricyclic thiazepine derivative, 6-(p-tolyl)benzo[f] pyrido[2,3-b][1,4] thiazepine 11,11-dioxide (TBPT), exhibits potent inhibitory effects in two non-small-cell lung cancer cell lines, H460 and its drug-resistant variant, H460TaxR, while exhibiting much less toxic effects on normal human fibroblasts. After five injections of TBPT at a dose of 60 mg/kg, it inhibits H460TaxR tumor growth in xenografted mouse models by 66.7% without causing observable toxicity to normal tissues. Based on gene perturbation data and a series of investigations, we reveal that TBPT is not a P-glycoprotein substrate and it inhibits microtubule formation by targeting tubulin, thereby causing cell cycle arrest at the G2/M stage and eventually inducing apoptosis. This redeployment of antidepressant compound scaffold for anticancer applications provides a promising future for conquering drug-resistant tumors with fewer side effects.

Synthesis and biological evaluation of indole-2-carbohydrazides and thiazolidinyl-indole-2-carboxamides as potent tubulin polymerization inhibitors

A new series of N?-(substituted phenyl)-5-chloro/iodo-3-phenyl-1H-indole-2-carbohydrazide (5, 6) and N-[2-(substituted phenyl)-4-oxo-1,3-thiazolidin-3-yl]-5-iodo/chloro-3-phenyl-1H-indole-2-carboxamide (7, 8) derivatives were synthesized and evaluated for their anticancer properties. Compounds 5a and 6b, selected as prototypes by the National Cancer Institute for screening against the full panel of 60 human tumor cell lines at a minimum of five concentrations at 10-fold dilutions, demonstrated remarkable antiproliferative activity against leukemia, non-small cell lung cancer, colon cancer, central nervous system (CNS) cancer, melanoma, ovarian cancer, renal cancer, and breast cancer (MCF-7) cell lines with GI50 values < 0.4 muM. A subset of the compounds was then tested for their potential to inhibit tubulin polymerization. Compounds 6f and 6g showed significant cytotoxicity at the nM level on MCF-7 cells and exhibited significant inhibitory activity on tubulin assembly and colchicine binding at about the same level as combretastatin A-4. Finally, docking calculations were performed to identify the binding mode of these compounds. Group 5 and 6 compounds interacted with the colchicine binding site through hydrophobic interactions similar to those of colchicine. These compounds with antiproliferative activity at high nanomolar concentration can serve as scaffolds for the design of novel microtubule targeting agents.

Open source drug discovery: Highly potent antimalarial compounds derived from the tres cantos arylpyrroles

The development of new antimalarial compounds remains a pivotal part of the strategy for malaria elimination. Recent large-scale phenotypic screens have provided a wealth of potential starting points for hit-to-lead campaigns. One such public set is explored, employing an open source research mechanism in which all data and ideas were shared in real time, anyone was able to participate, and patents were not sought. One chemical subseries was found to exhibit oral activity but contained a labile ester that could not be replaced without loss of activity, and the original hit exhibited remarkable sensitivity to minor structural change. A second subseries displayed high potency, including activity within gametocyte and liver stage assays, but at the cost of low solubility. As an open source research project, unexplored avenues are clearly identified and may be explored further by the community; new findings may be cumulatively added to the present work.

Synthesis of 2-oxazolidones by sulfur-assisted thiocarboxylation with carbon monoxide and oxidative cyclization with molecular oxygen under mild conditions

Simple synthetic method on 2-oxazolidone derivatives was established. 2-Aminoethanols were easily subjected to the thiocarboxylation with carbon monoxide promoted by elemental sulfur, followed by the oxidative cyclization with molecular oxygen to give corresponding 2-oxazolidones in good yields under mild conditions (1 atm, rt). Furthermore, 2-imidazolidones and 2-thiazolidone were also prepared in good yields similarly.

Molecules with versatile biological activities bearing antipyrinyl nucleus as pharmacophore

Antipyrine (1,2-dihydro-1,5-dimethyl-2-phenylpyrazole-3-one) in a structural frame consists of a five membered lactam pyrazolone heterocyclic ring as a pharmacophore moiety. It is evident from literature that the molecules having nitrogen bearing heterocyclic nuclei clearly exhibit several biological actions. Commercially available pyrazolone derivatives as drugs, analgin and metamizol are an established chemical class of analgesics. Recent trends of synthetic routes and several biological actions of antipyrine analogues are considered in this review. Indeed, the synthesized derivatives possess antipyrine moiety having versatile biological properties, antimicrobial, antitubercular, anthelmintic, antioxidant, analgesic, anti-inflammatory, cytotoxic and antiviral activities.
