Epidermal Growth Factor Receptor (EGFR) is a transmembrane glycoprotein that constitutes one of the four members of ErbB family of tyrosine kinase receptors. Activation of EGFR leads to autophosphorylation of receptor tyrosine kinase that initiates a cascade of downstream signaling pathways involved in regulating cellular proliferation, differentiation, and survival. EGFR is abnormally activated by various mechanisms like receptor overexpression, mutation, ligand-dependent receptor dimerization, ligand-independent activation and is associated with the development of variety of human cancers. EGFR inhibition is one of the key targets for cancer chemotherapy. Approval of tyrosine kinase inhibitors such as erlotinib, gefitinib, and lapatinib for the treatment of non-small cell lung cancer led to tremendous development of novel EGFR inhibitors in the last decade. Diverse class of chemical compounds from the synthetic origin has been extensively studied. This review highlights the various classes of synthetically derived molecules which have been reported in the last few years as potential EGFR and EGFR/ErbB-2 dual inhibitors. A brief synthetic methodology to access these compounds has been highlighted along with the SAR. We strongly believe that this review will provide a platform to the synthetic chemists and biologists to design and synthesize new and potent compounds that inhibit EGFR and ErbB-2.

4-(6-Fluoro-1,2-benzisoxazol-3-yl)piperidine has been linked to various arylcarbamates to obtain compounds having affinity for dopamine-D1 and -D2, serotonin 5HT(2A) and alpha1-adrenoceptors. When linkers with restricted flexibility are used, the biological activity is reduced indicating that a bended conformation is needed in this series of bioactive molecules. Compounds with a relatively low D2/5HT(2A) affinity ratio in receptor binding experiments and high affinity for the alpha1-adrenoceptors exhibit a pharmacological profile which suggests a preferential effect on the mesocorticolimbic dopaminergic system and an ‘atypical’ antipsychotic activity.

Chiral biphenols catalyze the asymmetric Petasis borono-Mannich allylation of aldehydes and amines through the use of a bench-stable allyldioxaborolane. The reaction proceeds via a two-step, one-pot process and requires 2?8 mole % of 3,3?-Ph2-BINOL as the optimal catalyst. Under microwave heating the reaction affords chiral homoallylic amines in excellent yields (up to 99 %) and high enantioselectivies (er up to 99:1). The catalytic reaction is a true multicomponent condensation reaction whereas both the aldehyde and the amine can possess a wide range of structural and electronic properties. Use of crotyldioxaborolane in the reaction results in stereodivergent products with anti- and syn-diastereomers both in good diastereoselectivities and enantioselectivities from the corresponding E- and Z-borolane stereoisomers.

Acetaldehyde dehydrogenase (AdhE) is a bifunctional acetaldehyde?coenzyme A (CoA) dehydrogenase and alcohol dehydrogenase involved in anaerobic metabolism in gram-negative bacteria. This enzyme was recently found to be a key regulator of the type three secretion (T3S) system in Escherichia coli. AdhE inhibitors can be used as tools to study bacterial virulence and a starting point for discovery of novel antibacterial agents. We developed a robust enzymatic assay, based on the acetaldehyde-CoA dehydrogenase activity of AdhE using both absorption and fluorescence detection models (Z? > 0.7). This assay was used to screen ~11,000 small molecules in 384-well format that resulted in three hits that were confirmed by resynthesis and validation. All three compounds are noncompetitive with respect to acetaldehyde and display a clear dose?response effect with hill slopes of 1?2. These new inhibitors will be used as chemical tools to study the interplay between metabolism and virulence and the role of AdhE in T3S regulation in gram-negative bacteria, and as starting points for the development of novel antibacterial agents.

Redox catalysis has been broadly utilized in electrochemical synthesis due to its kinetic advantages over direct electrolysis. 39270-39-8, Name is (2,3-Dihydrobenzo[b][1,4]dioxin-6-yl)methanol. In a Article, once mentioned of 39270-39-8.

Reaction of 2′-benzylbenzohydrazides with concentrated polyphosphoric acid gave 2,5-diaryl-1,3,4-oxadiazoles and a polybenzyl.Cyclodehydration to phthalazines was not observed.It is inferred from product substitution patterns that CH2-N bond cleavage occurs with polybenzyls forming from the benzyl moiety and oxadiazoles from the benzohydrazide fragment.Other reported reactions which generate benzyl fragments lead to bibenzyl and are considered to involve trapping of the cleavage products within a solvent cage.The observed production of polybenzyls is therefore interpreted in terms of the formation of free benzyl fragments.A tetrahydrophthalazine derivative was produced from the addition of diethyl azodicarboxylate to the photodiene of o-methylbenzophenone, but this could not be converted into a phthalazine.

We recently identified a peptide-peptoid hybrid, PPS1, which specifically recognized lipid-phosphatidylserine (PS). PPS1 consists of distinct positively charged and hydrophobic residue-containing regions. The PPS1 monomer was inactive, but the dimeric form, PPS1D1, displayed strong cytotoxicity to lung cancer cells compared to normal cells in vitro, and reduced the tumor growth in vivo. The minimum pharmacophore of PPS1D1 showed that the first (methionine) and fourth (N-lysine) residues were not important for PPS1D1 cytotoxic activity. In this study, we further investigated these two residues, in particular the fourth residue that lies between the most important four-residue hydrophobic region and two positively charged residues, to determine whether replacements of these moieties could gain activity improvements or render PPS1D1 totally insensitive for binding recognition. The positively charged fourth residue N-lysine was replaced with substituents having varied physiochemical properties, such as aromatic-hydrophobic, aliphatic-alicyclic, heterocyclic, and negatively charged residues, developing a mini-library of 39 derivatives. The standard 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium (MTS) colorimetric and/or the calcein AM cell viability assays performed on HCC4017 lung cancer cells indicated that the fourth position of PPS1D1 was insensitive to most changes, except that reversal of the negative charge significantly affected the activity. This observation may be due to the neutralization of the nearby positively charged residue that is essential for binding. In addition, shortening each monomeric sequence by eliminating the methionine at the first position did not affect the activity.
