Abstract:
The oxidative chemical polymerizations of three isomers of aminophenol,ortho,meta, andpara(PoAP, PmAP, and PpAP), were performed in aqueous HCl using ammonium persulfate as an oxidant at 0–3°C. The synthesized polymers were characterized by employing elemental analysis, GPC, UV-VIS-NIR, FT-IR, XRD, and TGA. The corrosion inhibition effect of these three polymers on mild steel in 1 M HCl solution was studied by using electrochemical techniques such as potentiodynamic polarization and electrochemical impedance spectroscopy. These measurements reveal that the inhibition efficiency obtained by the

Gold catalysis has become an important tool to achieve highly chemoselective p-acid activation. Exceptional reactivity and selectivity are often encountered under mild reaction conditions. These properties have made gold(I) complexes suitable catalysts for tremendous applications in the total synthesis of natural products. The first chapter will highlight a number of total syntheses using gold catalysis as a key step. The second chapter will cover our application of the gold(I)-catalyzed 6-endo-dig carbocyclization for the synthesis of bridgehead-substituted scaffolds and its use toward the

PPAPs have been of interest to the scientific community for their intricate structure, their powerful aid in treating many ailments and large portfolio of biological activities. More particularly, they have been of synthetic interest since 1999 with the first report of an approach to these complicated cores by Nicolaou. Herein, we present the first tot

Plants of the family Guttiferae produce polycyclic polyprenylated acylphloroglucinols (PPAPs), which have interesting biological activities including anticancer and antibacterial properties. The main structural features of PPAPs comprise of bicyclo[3.3.1]nonane-2,4,9-triketone with one acyl group together with prenyl, geranyl, or other C10H17 groups. 7-epi-Clusianone, a type B PPAP with C-7 endo stereochemistry, is being approached by establishing the cis relationship with C(4) allyl group and C(2) methyl ester in the early stage of the synthesis. Then C(2) methyl ester is converted to alkyne

Obesity constitutes a problem whose manifestations have consequences in almost every field of the medicine and nowadays there is a lack of pharmacological therapy alternatives for its long term treatment. Lipidic compounds as endocannabinoids and PPAR-α ligands are known to play an important role in the modulation of appetite and metabolism. Three series of fatty acid derivatives of catechol compounds were synthesized and their biological activity evaluated. Some of the synthesized compounds presented LDL antioxidant activity and/or food intake modulation in an animal model and their

Abstract:
Abstract The objective of this paper is to derive analytically the circle-point and center-point curve equations for the synthesis of four-bar linkages for rigid body guidance through four multiply separated design positions. A unified approach is evolved to deal with the different combinations of four finitely and infinitesimally separated design position, namely the PP-P-P, PP-PP and PPP-P cases. The design procedure incorporates the rectification procedures developed by Waldron (1977) to eliminate the branch and order problems and is implemented in the interactive synthesis package RECSYN.

A role for the Platelet Derived Growth Factor (PDGF) has been suggested in the abnormal proliferation of bone marrow fibroblasts occuring during myelofibrosis. To investigate this hypothesis, human bone marrow fibroblasts were isolated, and the cultures were characterized by immunofluorescent staining and electron microscopy. Electron microscopy eliminated the presence of endothelial cells by the absence of Weibel-Palade-Bodies. A positive intra and extra cellular antifibro-nectin staining was observed by immunofluorescent staining. The cultured cells didn’t show any labeling with specific ant
