In this review, we show how chromaffin cells have contributed to evaluate neuroprotective compounds with diverse mechanisms of action. Chromaffin cells are considered paraneurons, as they share many common features with neurons: (i) they synthesize, store, and release neurotransmitters upon stimulation and (ii) they express voltage-dependent calcium, sodium, and potassium channels, in addition to a wide variety of receptors. All these characteristics, together with the fact that primary cultures from bovine adrenal glands or chromaffin cells from the tumor pheochromocytoma cell line PC12 are easy to culture, make them an ideal model to study neurotoxic mechanisms and neuroprotective drugs. In the first part of this review, we will analyze the different cytotoxicity models related to calcium dyshomeostasis and neurodegenerative disorders like Alzheimer?s or Parkinson?s. Along the second part of the review, we describe how different classes of drugs have been evaluated in chromaffin cells to determine their neuroprotective profile in different neurodegenerative-related models.

Objective: The hyrtimomine A-K class of indole-based compounds extracted from Hyrtios spp. of sponges from the sea has not been studied for their anticancer properties. Phosphoinositide-dependent kinase 1 (PDK1) is a master regulator of many types of cancer. Compounds currently targeting PDK1 are currently of poor specificity and solubility. Hence, molecular docking to look for new compounds inhibiting PDK1 from the marine environment was carried out. Methods: Target selection for ligands hyrtimomine A-K was done using PharmMapper tool. Molecular docking was done using iGEMDOCK 2.1, a generic evolutionary method of docking. Site moiety mapping was done in SimMap to extract the anchor preference of the top hits. Comparison of ligand binding energies, pharmacokinetic properties with lead compound BX-517 was carried out. Results: Hyrtimomine B, C, D, and G were top hits using iGEMDOCK. The highest score was obtained for hyrtimomine C. Van der Waals interaction at T222 and V96 and hydrogen bond interaction at K111 determined pocket stability. The solubility properties of the compound showed higher score for hyrtimomine C. The conserved features of hyrtimomine C were then compared with the crystal structure of lead compound (BX-517, which was not developed further due to poor solubility and bioavailability). The pharmacokinetic properties of hyrtimomine C were superior to BX-517 and had better solubility and drug-likeness score, hence, may be a candidate structure for drug development. Conclusion: The unique azapeno indole structure of hyrtimomine C highlighted the mode of binding and residues in binding site.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.name: 1,8-Diazanaphthalene, you can also check out more blogs about254-60-4

Protein farnesyltransferase (PFT) inhibitors have emerged as a potent target for the malaria treatment caused by the Plasmodium falciparum (Pf) parasite. In this review, various scaffolds as Pf-PFT inhibitors are reported. Seven inhibitor scaffolds based on ethylenediamine, peptidomimetic, benzophenone, benzamide, tetrahydroquinoline, naphthyridine and oxy-tetrahydroquinoline, have been developed. These inhibitors act against Pf-PFT target and have proved their therapeutic potential as antimalarial agents. This review is primarily meant for suggesting new drugs against malaria.

Because traditional approaches to drug development for Alzheimer’s disease are becoming increasingly expensive and in many cases disappointingly unsuccessful, alternative approaches are required to shift the paradigm. Following leads from investigations of dihydropyridine calcium channel blockers, we observed unique properties from a class of functionalized naphthyridines and sought to develop these as novel therapeutics that minimize amyloid pathology without the adverse effects associated with current therapeutics. Our data show methyl 2,4-dimethyl-5-oxo-5,6-dihydrobenzo[c][2,7]naphthyridine-1-carboxylate (BNC-1) significantly decreases amyloid burden in a well-established mouse model of amyloid pathology through a unique mechanism mediated by Elk-1, a transcriptional repressor of presenilin-1. Additionally, BNC-1 treatment leads to increased levels of synaptophysin and synapsin, markers of synaptic integrity, but does not adversely impact presenilin-2 or processing of Notch-1, thus avoiding negative off target effects associated with pan-gamma secretase inhibition. Overall, our data show BNC-1 significantly decreases amyloid burden and improves markers of synaptic integrity in a well-established mouse model of amyloid deposition by promoting phosphorylation and activation of Elk-1, a transcriptional repressor of presenilin-1 but not presenilin-2. These data suggest BNC-1 might be a novel, disease-modifying therapeutic that will alter the pathogenesis of Alzheimer’s disease.

Several bis-chelated palladium(II)complexes, [Pd(PP)(N-N)(x)](PF6)2, containing binary combinations of diphosphine and dinitrogen ligands have been prepared and characterized. The diphosphine ligands comprise 1,3- bis(diphenylphosphino)propane (dppp), meso-2,4-bis(diphenylphosphino)pentane (meso-bdpp), rac-2,4-bis(diphenylphosphino)pentane (rac-bdpp) and 2,2′- bis(diphenylphosphinoethyl)pentane (Etdppp), while the dinitrogen ligands are either 2,2′-bipyridine (bipy; x = 1) or 1,8-naphthyridine (napy; x = 2). The structure of [Pd(meso-bdpp)(N,N’-bipy)](PF6)2 ¡¤ CH2Cl2 has been determined by an X-ray structural analysis. All the Pd(II) complexes have been tested as catalyst precursors for the copolymerization of carbon monoxide and ethene in methanol solution in either autoclaves or high- pressure sapphire NMR tubes. The combination of meso-bdpp and bipy at palladium, in conjuction with both 1,4-benzoquinone and p-toluenesulfonic acid, has shown the best catalytic performance. The different catalytic activities exhibited by the stereoisomers [Pd(meso-bdpp)(N,N’-bipy)](PF6)2 and [Pd(rac-bdpp)(N,N’-bipy)](PF6)2 has been interpreted in terms of the different spatial distribution of the phenyl rings around the metal center determined by the conformation of the six-membered metallaring.

A highly efficient stereoselective synthesis of CF3-oxazinoquinolines was elaborated using the reaction of CF3-ynones with quinolines in water. It was demonstrated that under these green conditions, the reaction proceeds up to 20 times faster to provide target compounds in almost quantitative yields. Moreover, this method is devoid of any chromatographic purification to give CF3-oxazinoquinolines with complete diastereoselectivity. The presented eco-friendly approach was found much more efficient than standard reactions in organic solvents. The synthetic utility of the prepared CF3-oxazinoquinolines was demonstrated.

In order to include the design capability for a compound rotorcraft in a helicopter conceptual design and optimization framework, relevant further improvement was planned and conducted. Previously, a certain conceptual design optimization framework was developed by the present authors to design a modern rotorcraft with single main and tail rotor. The previously developed framework was further improved to expand its capability for a compound rotorcraft. Specifically, its power estimation algorithm was upgraded by using a comprehensive rotorcraft analysis program, CAMRAD II. The presently improved conceptual design and optimization framework was validated using data of the XH-59A aircraft.
