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.

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.

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.

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.

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.

Alk-1-enesulfonic acids and derivatives (update 2018)

This update covers new information regarding methods for the preparation of alk-1-enesulfonic acids and derivatives and their application in synthesis published since 2004. Aryl ethenesulfonates and aryl vinyl sulfones are a new class of mechanism-based probes of the protein tyrosine phosphatases.[1] Ethenesulfonates and vinyl sulfones inactivate a large variety of protein tyrosine phosphatases in a time- A nd concentration-dependent fashion. This inactivation by Michael addition of the cysteine residue is active-site-directed and irreversible. The relative rates of base-promoted Michael additions to several alk-1-enyl sulfonyl compounds were measured by 1HNMR spectroscopy. Phenyl (E)-3-[(benzyloxycarbonyl)amino]-3-phenylprop-1-ene-1-sulfonate undergoes conjugate addition at a rate ca. 3000-fold higher than that of the corresponding (E)-N-benzyl-3-[(benzyloxycarbonyl) amino]-3-phenylprop-1-ene-1-sulfonamide derivative.[2] The novel alkenesulfonic acid derivative celtisanin (1) has been isolated from the fruits of the tree Celtis australis (Ulmaceae) which grows in the montane and submontane Himalayan regions in India (Scheme 1).[3] The plant is known as traditional medicine for various ailments. The structure of celtisanin has been established using MS and NMR spectroscopy.

Catalyst-free N-methylation of amines using CO2

Recently, utilizing CO2 as a methylation reagent to construct functional chemicals has attracted significant attention. However, the conversion of CO2 is still a challenge due to its inherent inertness. In this study, we have developed a catalyst-free N-methylation of amines to prepare numerous methylamines using CO2 as a methyl source. By utilizing 2 eq. PhSiH3 as the reductant, amines could undergo N-methylation under 1 atm of CO2 in DMF at 90 C. Aliphatic and aromatic amines were compatible, generating the desired products in up to 95% yield.

Insight into sulfamethoxazole degradation, mechanism, and pathways by AgBr-BaMoO4 composite photocatalyst

A composite photocatalyst, AgBr-BaMoO4 was fabricated by two step method; microwave hydrothermal and precipitation-deposition. The as prepared photocatalyst samples were characterized by various techniques. The facet coupling was seen between the (204) plane of BaMoO4 and (200)/(222) planes of AgBr on the basis of XRD/HRTEM analysis. The pharmaceutical pollutant, sulfamethoxazole was adopted to investigate the photocatalytic performances of samples under UV?vis irradiation. The AgBr-BaMoO4 composite degraded the aqueous sulfamethoxazole drug in UV?vis light about 64% within 75 min, which was attributed to efficient separation of photogenerated electron?hole pairs across the interface between Ag/AgBr and BaMoO4. The multi-electron induced oxygen reduced reaction (ORR) was observed. The radical trapping experiment indicates that OH? has major role for sulfamethoxazole degradation. The four successive photodegradation of sulfamethoxazole in UV?vis light indicates the stability of composite photocatalyst. Furthermore, the three different degradation pathways were designed on the basis of retention time and molecular masses of 18 degraded organic fragments that was confirmed by high-performance liquid chromatography photodiode array (HPLC-PDA) and high resolution-quadruple time of flight electrospray ionization mass spectroscopy (HR-QTOF ESI/MS) techniques. The total organic carbon (TOC) analysis suggested the mineralization of SMZ by composite photocatalyst. This study not only demonstrates the enhancement of photocatalytic performance of wide band gap semiconductor by making composite with narrow band gap semiconductor but also detail degradation pathways and mechanisms of sulfamethoxazole.
