Three organic compounds containing azole rings 1-benzyl-4-phenyl-1H-1,2,3-triazole (I1), 5-phenyl-3-propylisoxazole (I2), and 3,5-diphenylisoxazole (I3) were synthesized and characterized as corrosion inhibitors on galvanized steel and copper-nickel (Cu-Ni, 90/10) substrates. The three tested azole inhibitors acted as corrosion inhibitors on galvanized steel in the presence of real cooling water used as electrolyte. Electrochemical performance indicated that the presence of heteroatoms, such as N and O, with free pair electrons, the chain length, and the aromatic ring plays an important role in the capacity to inhibit corrosion of galvanized steel. 3,5-diphenylisoxazole (I3) has the best inhibition activity with jcorr of 2.04 × 10?7 (5 ppm), 7.57 × 10?8 (10 ppm), and 1.73 × 10?8 (20 ppm) A cm?2, followed by compounds I1 and I2. The synthesized compounds are comparable or even higher than the electrochemical performance of commercial inhibitor tolyltriazole (TTA, jcorr = 3.06 × 10?8 A cm?2). Conversely, for Cu-Ni (90/10) substrates, commercial TTA with 20 ppm displayed the lowest corrosion current densities (jcorr = 3.20 × 10?8 A cm?2) through a characteristic anodic pseudo-passivation; however, pits were observed after ~550 mVAg/AgCl. In contrast, the synthesized compounds tended to suppress anodic copper dissolution at positive potentials but, in the best case, displayed greater corrosion rates I3 (1.463 mils per year (MPY)), I2 (1.515 MPY), and I1 (0.677 MPY) in comparison with TTA (0.091 MPY). The low inhibition efficiency (IE) of synthesized compounds is correlated to the weak absorption on the copper surface.

Mitochondrial dysfunction is a central protagonist of Alzheimer’s disease (AD) pathogenesis. Mitochondrial dysfunction stems from various factors including mitochondrial DNA damage and oxidative stress from reactive oxygen species, membrane and ionic gradient destabilization, and interaction with toxic proteins such as amyloid beta (Abeta). Therapeutic drugs such as cholinesterase and glutamate inhibitors have proven to improve synaptic neurotransmitters, but do not address mitochondrial dysfunction. Researchers have demonstrated that oxidative damage may be reduced by increasing endogenous antioxidants, and/or increasing exogenous antioxidants such as vitamin C & E, beta-carotene and glutathione. Nonetheless, as AD pathology intensifies, endogenous antioxidants are overwhelmed, and exogenous antioxidants are unable to reach neuronal mitochondria as they are blocked by the blood brain barrier. Current therapeutic methods however include novel usage of lipophilic phosphonium cation bound to antioxidants, to effect neuronal mitochondria targeted activity. Mitochondria targeted MitoQ, MitoVitE, MitoTempo, MitoPBN and MCAT concentrate within mitochondria where they scavenge free-radicals, and augment mitochondrial dysfunction. Additional molecules include Szeto-Schiller (SS) peptides which target stability of the inner mitochondrial membrane, and DDQ molecule capable of improving bioenergetics and reduce mitochondrial fragmentation. This article discusses advantages and disadvantages of small molecules, their ability to mitigate Abeta induced damage, and ability to ameliorate synaptic dysfunction and cognitive loss.

Background: Induced Pluripotent Stem Cell (IPSC) Technology is the most advanced research as it offers an attractive alternative for establishing patient-specific IPSCs to recapitulate phenotypes of not only monogenic diseases (viz. Thalassaemia, Sickle cell anemia, Haemophilia, Tay-Sachs disease), but also late-onset polygenic diseases (viz. Parkinson’s disease, Alzheimer’s disease, schizophrenia). Over the hindsight, numerous studies of the past and current scientists have led to the production, maturation and understanding of induced pluripotent stem cell technology and its use in basic and clinical research. Methods: A systematic search of peer-reviewed scientific literature and clinical trials in public databases were carried out to summarize the evidence on the use of IPSC. Results: Current review sheds light upon the use of patient-derived iPSC models in drug toxicity, screening and discovery which have been derived after referring to more than 200 articles in literature. Furthermore, their use as disease models was also studied signifying the versatility of iPSC lines. Conclusion: Through this review, we describe the advent of iPSC technology, where we comprehensively cover the generation of iPSCs and their characterization along with their prospective applications using IPSC banks in disease modeling and drug screening.

Background: Design and synthesis of new inhibitor agents to deal with pathogenic microorganisms is expanding. In this project, an efficient, environmentally friendly, economical, rapid and mild procedure was developed for the synthesis of novel functionalized isoxazole derivatives as antimicrobial potentials. Methods: Multicomponent reaction between malononitrile (1), hydroxylamine hydrochloride (2) and different aryl or heteroaryl aldehydes 3a-i afforded novel 5-amino-isoxazole-4-carbonitriles 4a-i in good product yields and short reaction times. Deep eutectic solvent K2CO3/glycerol was used as catalytic reaction media. Structure of all molecules were characterized by different analytical tools. In vitro inhibitory activity of all derivatives was evaluated against a variety of pathogenic bacteria including both Gram-negative and Gram-positive strains as well as some fungi. In addition, their free radical scavenging activities were assessed against DPPH. Results: Broad-spectrum antimicrobial activities were observed with isoxazoles 4a, b, d. In addition, antioxidant activity of isoxazole 4i was proven on DPPH. Conclusions: In this project, compounds 4a, b, d could efficiently inhibit the growth of various bacterial and fungal pathogens. Antioxidant properties of derivative 4i were also significant. These biologically active compounds are suitable candidates to synthesize new prodrugs and drugs due to the presence of different functional groups on their rings.

A bidentate Schiff base Salicylidene-sulphamethoxazole synthesized from sulphamethoxazole and salicyladehyde, form stable complexes with organyltellurium(IV) trichlorides and diorganryltellurium(IV) dichlorides of the type Sal-SMZ.RTeCl2 and Sal-SMZ.R2TeCl (where R = 4-methoxyphenyl, 4-ethoxyphenyl, 4-hydroxyphenyl and 3-methyl-4-hydroxyphenyl and Sal-SMZ = Schiff base). Their structures were investigated by elemental analyses, molar conductance, FT-IR and 1H NMR spectroscopy.

Two series of new pyrazoline and isoxazole bridged indole C-glycoside molecular hybrids (n = 36) were efficiently synthesized starting from diverse indole 3-carboxaldehydes derived alpha, beta-unsaturated ketone derivatives of beta-D-glucosyl-propan-2-one, beta-D-galactosyl-propan-2-one and beta-D-mannosyl-propan-2-one, reacting with hydrazine hydrate and hydroxyl amine hydrochloride in shorter reaction time (15 min) under microwave assisted condition. Anticancer activity of these newly synthesized pyrazoline and isoxazole bridged indoles C-glycoside hybrids were determined in details through cellular assays against MCF-7, MDA-MB-453 and MDA-MB-231 cancer cell lines. The selected library members displayed low micromolar (IC50 = 0.67?4.67 muM) and selective toxicity against breast cancer cell line (MCF-7). Whereas these compounds were nontoxic towards normal cell line (MCF-10A). Mechanistic studies showed that, active compounds inhibit COX-2 enzyme, which was also supported by molecular docking studies. These findings are expected to provide new leads towards anticancer drug discovery.

Results: The salicylic acid is found to possess acceptable catalytic activity for the promotion of three-component cyclocondensation of aryl/heteroaryl aldehydes, beta-ketoesters, and hydroxylamine hydrochloride. The three-component reaction led to construction of 3-substituted-4-arylmethylideneisoxazol-5(4H)-ones in good to high isolated reaction yields. Conclusion: The efficient and environmental friendliness procedure for the synthesis of isoxazol-5(4H)-ones is introduced. The reaction also carried out smoothly in water as a cost-effective, simple, green, and non-toxic solvent at room temperature without using heating, microwave, and ultrasound sources.
