Remodelling of the natural product fumagillol employing a reaction discovery approach

In the search for new biologically active molecules, diversity-oriented synthetic strategies break through the limitation of traditional library synthesis by sampling new chemical space. Many natural products can be regarded as intriguing starting points for diversity-oriented synthesis, wherein stereochemically rich core structures may be reorganized into chemotypes that are distinctly different from the parent structure. Ideally, to be suited to library applications, such transformations should be general and involve few steps. With this objective in mind, the highly oxygenated natural product fumagillol has been successfully remodelled in several ways using a reaction-discovery-based approach. In reactions with amines, excellent regiocontrol in a bis-epoxide opening/cyclization sequence can be obtained by size-dependent interaction of an appropriate catalyst with the parent molecule, forming either perhydroisoindole or perhydroisoquinoline products. Perhydroisoindoles can be further remodelled by cascade processes to afford either morpholinone or bridged 4,1-benzoxazepine-containing structures.

Synthesis, docking, antioxidant, antihyperlipidemic, antiplatelet, anticoagulant, and vasodilatory activities of isoxazole newly synthesized derivative

We synthesized isoxazole derivative: 4-({4-(dimethylamino) phenyl}methylidene)-3-methyl-1,2-isoxazole-5(4H)-one (PMX-5), characterized by FTIR,1H-NMR and13C-NMR. In computational anal-ysis, PMX-5 showed high affinity for farnesoid X receptor, glycoprotein-VI, vitamin-K epoxide reductase, and guanylyl cyclase. At concentrations of 1, 3, 10, 100, 300, 700, and 1000 mug/mL, it exhibited free radical scavenging effect as 3.2743 ¡À 0.48, 10.8036 ¡À 2.79, 15.2931 ¡À 3.38, 29.6991 ¡À 0.08, 37.2992 ¡À .59, 47.4319 ¡À 0.51, and 63.5001 ¡À 1.23%, respectively. In high fat diet-induced hyperlipidemia, PMX-5 lowered total cholesterol, triglyceride, low-density lipoprotein, and very low-density lipoprotein levels, while elevated high-density lipoprotein levels significantly (p < 0.001 vs. saline) in rats. PMX-5 suppressed arachidonic acid and adenosine diphosphate-induced platelet aggregation with IC50 values of 192 and 831 muM, respec-tively. It also showed anticoagulant potential by increasing plasma recalcification time to 101.2 ¡À 2.4 s at 30 muM, 108 ¡À 2.2 s at 100 muM, 132.2 ¡À 2.9 and 202.4 ¡À 4.6 s (p < 0.001) at 300 and 1000 muM, respectively. PMX-5 partly relaxed phenylephrine and K+ (80 mM)-induced contractions in isolated rat aortic tissues. Thus, the current study reports the synthesis of PMX-5 and its pharmacological potentials. The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.

Human galectin-1 and its inhibitors: Privileged target for cancer and HIV

Galectin 1(Gal-1), a beta-galactoside binding mammalian lectin of 14KDa, is implicated in many signalling pathways, immune responses associated with cancer progression and immune disorders. Inhibition of human Gal-1 has been regarded as one of the potential therapeutic approaches for the treatment of cancer, as it plays a major role in tumour development and metastasis by modulating various biological functions viz. apoptosis, angiogenesis, migration, cell immune escape. Gal-1 is considered as a biomarker in diagnosis, prognosis and treatment condition. The overexpression of Gal-1 is well established and seen in many types of cancer progression like osteosarcoma, breast, lung, prostate, melanoma, etc. Gal-1 greatly accelerates the binding kinetics of HIV-1 to susceptible cells, leading to faster viral entry and a more robust viral replication by specific binding of CD4 cells. Hence, the Gal-1 is considered a promising molecular target for the development of new therapeutic drugs for cancer and HIV. The present review laid emphasis on structural insights and functional role of Gal-1 in the disease, current Gal-1 inhibitors and future prospects in the design of specific Gal-1 inhibitors.

Identifying mechanism-of-action targets for drugs and probes

Notwithstanding their key roles in therapy and as biological probes, 7% of approved drugs are purported to have no known primary target, and up to 18% lack a well-defined mechanism of action. Using a chemoinformatics approach, we sought to “de-orphanize”drugs that lack primary targets. Surprisingly, targets could be easily predicted for many: Whereas these targets were not known to us nor to the common databases, most could be confirmed by literature search, leaving only 13 Food and Drug Administration – approved drugs with unknown targets; the number of drugs without molecular targets likely is far fewer than reported. The number of worldwide drugs without reasonable molecular targets similarly dropped, from 352 (25%) to 44 (4%). Nevertheless, there remained at least seven drugs for which reasonable mechanism-of-action targets were unknown but could be predicted, including the antitussives clemastine, cloperastine, and nepinalone; the antiemetic benzquinamide; the muscle relaxant cyclobenzaprine; the analgesic nefopam; and the immunomodulator lobenzarit. For each, predicted targets were confirmed experimentally, with affinities within their physiological concentration ranges. Turning this question on its head, we next asked which drugs were specific enough to act as chemical probes. Over 100 drugs met the standard criteria for probes, and 40 did so by more stringent criteria. A chemical information approach to drug-target association can guide therapeutic development and reveal applications to probe biology, a focus of much current interest.

Cross-beta polymerization of low complexity sequence domains

Most transcription factorsand RNA regulatory proteins encoded by eukaryotic genomes ranging from yeast to humans contain polypeptide domains variously described as intrinsically disordered, prion-like, or of low complexity (LC). These LC domains exist in an unfolded state when DNA and RNA regulatory proteins are studied in biochemical isolation from cells. Upon incubation in the puri?ed state, many of these LC domains polymerize into homogeneous, labile amyloid-like ?bers. Here, we consider several lines of evidence that may favor biologic utility for LC domain polymers.

Structure-based design, synthesis, and characterization of inhibitors of human and Plasmodium falciparum dihydroorotate dehydrogenases

Pyrimidine biosynthesis is an attractive drug target in a variety of organisms, including humans and the malaria parasite Plasmodium falciparum. Dihydroorotate dehydrogenase, an enzyme catalyzing the only redox reaction of the pyrimidine biosynthesis pathway, is a well-characterized target for chemotherapeutical intervention. In this study, we have applied SPROUT-LeadOpt, a software package for structure-based drug discovery and lead optimization, to improve the binding of the active metabolite of the anti-inflammatory drug leflunomide to the target cavities of the P. falciparum and human dihydroorotate dehydrogenases. Following synthesis of a library of compounds based upon the SPROUT-optimized molecular scaffolds, a series of inhibitors generally showing good inhibitory activity was obtained, in keeping with the SPROUTLeadOpt predictions. Furthermore, cocrystal structures of five of these SPROUT-designed inhibitors bound in the ubiquinone binding cavity of the human dihydroorotate dehydrogenase are also analyzed.

Pyridyl benzamides as a novel class of potent inhibitors for the kinetoplastid Trypanosoma brucei

A whole-organism screen of approximately 87000 compounds against Trypanosoma brucei brucei identified a number of promising compounds for medicinal chemistry optimization. One of these classes of compounds we termed the pyridyl benzamides. While the initial hit had an IC50 of 12 muM, it was small enough to be attractive for further optimization, and we utilized three parallel approaches to develop the structure-activity relationships. We determined that the physicochemical properties for this class are generally favorable with particular positions identified that appear to block metabolism when substituted and others that modulate solubility. Our most active compound is 79, which has an IC50 of 0.045 muM against the human pathogenic strain Trypanosoma brucei rhodesiense and is more than 4000 times less active against the mammalian L6 cell line.

Cardioselective antiischemic ATP-sensitive potassium channel (K(ATP)) openers. 5. Identification of 4-(N-aryl)-substituted benzopyran derivatives with high selectivity

This paper describes our studies aimed at the discovery of structurally distinct analogs of the cardioprotective K(ATP) opener BMS-180448 (2) with improved selectivity for the ischemic myocardium. The starting compound 6, derived from the indole analog 4, showed good cardioprotective potency and excellent selectivity compared to 2 and the first-generation K(ATP) opener cromakalim (1). The structure-activity studies indicate that increasing the size of the alkyl ester leads to diminished potency as does its replacement with a variety of other groups (nitrile, methyl sulfone). Replacement of the ethyl ester of 6 with an imidazole gave the best compound 3 (BMS-191095) of this series which maintains the potency and selectivity of its predecessor 6. The results described in this publication further support that there is no correlation between vasorelaxant and cardioprotective potencies of K(ATP) openers. Compound 3 is over 20- and 4000-fold more selective for the ischemic myocardium than 2 and cromakalim (1), respectively. The selectivity for the ischemic myocardium is achieved by reduction of vasorelaxant potency rather than enhancement in antiischemic potency. As for cromakalim (1) and 2, the cardioprotective effects of compound 3 are inhibited by cotreatment with the K(ATP) blocker glyburide, indicating that the K(ATP) opening is involved in its mechanism of cardioprotection. With its good oral bioavailability (47%) and plasma elimination half-life (3 h) in rats, compound 3 offers an excellent candidate to investigate the role of residual vasorelaxant potency of 2 toward its cardioprotective activity in vivo.

Ultrafast photodegradation of isoxazole and isothiazolinones by UV254 and UV254/H2O2 photolysis in a microcapillary reactor

The photodegradation process of methylisothiazolinone (MIT), benzisothiazolinone (BIT), and isoxazole (ISOX) in ultrapure water and synthetic wastewater by means of UV254 photolysis and by UV254/H2O2 advanced oxidation process were investigated in a microcapillary photoreactor designed for ultrafast photochemical transformation of microcontaminants. For the first time, we estimated key photo-kinetic parameters, i.e. quantum yields (35.4 mmol¡¤ein?1 for MIT, and 13.5 and 55.8 mmol¡¤ein?1 for BIT at pH = 4?6 and 8, respectively) and rate constants of the reaction of photo-generated OH radicals with MIT and BIT (2.09¡¤109 and 5.9¡¤109 L mol?1¡¤s?1 for MIT and BIT). The rate constants of the reaction of photo-generated OH radicals with ISOX in MilliQ water was also estimated (2.15¡¤109 L mol?1¡¤s?1) and it was in good agreement with literature indications obtained in different aqueous matrices. The models were extended and validated to the case of simultaneous degradation of mixtures of these compounds and using synthetic wastewater as an aqueous matrix. High resolution-accurate mass spectrometry analysis enabled identification of the main intermediates (BIT200, B200, saccharin, BIT166) and enabled proposal of a novel degradation pathway for BIT under UV254/H2O2 treatment. This study demonstrates an ultrafast method to determine key photo-kinetic parameters of contaminants of emerging concern in water and wastewater, which are needed for design and validation of photochemical water treatment processes of municipal and industrial wastewaters.
