In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Discovery of Leukotriene A4 Hydrolase Inhibitors Using Metabolomics Biased Fragment Crystallography, published in 2009-08-13, which mentions a compound: 83435-58-9, mainly applied to leukotriene hydrolase inhibitor drug discovery metabolomics crystallog structure activity; drug screening leukotriene hydrolase inhibitor preparation structure activity crystallog, Computed Properties of C10H19NO3.

We describe a novel fragment library termed fragments of life (FOL) for structure-based drug discovery. The FOL library includes natural small mols. of life, derivatives thereof, and biaryl protein architecture mimetics. The choice of fragments facilitates the interrogation of protein active sites, allosteric binding sites, and protein-protein interaction surfaces for fragment binding. We screened the FOL library against leukotriene A4 hydrolase (LTA4H) by X-ray crystallog. A diverse set of fragments including derivatives of resveratrol, nicotinamide, and indole were identified as efficient ligands for LTA4H. These fragments were elaborated in a small number of synthetic cycles into potent inhibitors of LTA4H representing multiple novel chemotypes for modulating leukotriene biosynthesis. Anal. of the fragment-bound structures also showed that the fragments comprehensively recapitulated key chem. features and binding modes of several reported LTA4H inhibitors.

The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: Boc-D-Prolinol, is researched, Molecular C10H19NO3, CAS is 83435-58-9, about The Discovery of Phthalazinone-Based Human H1 and H3 Single-Ligand Antagonists Suitable for Intranasal Administration for the Treatment of Allergic Rhinitis, the main research direction is phthalazinone derivative preparation intranasal antihistamine H1 H3 allergic rhinitis.Quality Control of Boc-D-Prolinol.

A series of potent phthalazinone-based human H1 and H3 bivalent histamine receptor antagonists, suitable for intranasal administration for the potential treatment of allergic rhinitis, were identified. Blockade of H3 receptors is thought to improve efficacy on nasal congestion, a symptom of allergic rhinitis that is currently not treated by current antihistamines. Two analogs (56a and 56b) had slightly lower H1 potency (pA2 9.1 and 8.9, resp., vs 9.7 for the clin. gold-standard azelastine), and H3 potency (pKi 9.6 and 9.5, resp., vs 6.8 for azelastine). Compound 56a had longer duration of action than azelastine, low brain penetration, and low oral bioavailability, which coupled with the predicted low clin. dose, should limit the potential of engaging CNS-related side-effects associated with H1 or H3 antagonism.

We’ll tell you more about this compound (cas:83435-58-9).

HYD1 is an all D-amino acid linear 10-mer peptide that was discovered by one-bead-one-compound screening. HYD1 has five hydrophobic amino acids flanked by polar amino acids. Alanine scanning studies showed that alternating hydrophobic amino acid residues and N- and C-terminal lysine side chains were contributors to the biol. activity of the linear 10-mer analogs. This observation led us to hypothesize that display of the hydrophobic pentapeptide sequence of HYD1 in a cyclic beta-hairpin-like scaffold could lead to better bioavailability and biol. activity. An amphipathic pentapeptide sequence was used to form an antiparallel strand and those strands were linked via dipeptide-like sequences selected to promote β-turns. Early cyclic analogs were more active but otherwise mimicked the biol. activity of the linear HYD1 peptide. The cyclic peptidomimetics were synthesized using standard Fmoc solid phase synthesis (Fmoc = 9-fluorenylmethoxycarbonyl) to form linear peptides, followed by solution phase or on-resin cyclization. SAR studies were carried out with an aim to increase the potency of these drug candidates for the killing of multiple myeloma cells in vitro. The solution structures of cyclic peptidomimetics were elucidated using NMR spectroscopy. 1H NMR and 2D TOCSY studies of these peptides revealed a downfield Hα proton chem. shift and 2D NOE spectral anal. consistent with a β-hairpin-like structure.

Effective delivery of therapeutic drugs into the human brain is one of the most challenging tasks in central nervous system drug development because of the blood-brain barrier (BBB). To overcome the BBB, both passive permeability and efflux transporter liability of a compound must be addressed. Herein, we report our optimization related to BBB penetration of neuronal nitric oxide synthase (nNOS) inhibitors toward the development of new drugs for neurodegenerative diseases. Various approaches, including enhancing lipophilicity and rigidity of new inhibitors and modulating the pKa of amino groups, have been employed. In addition to determining inhibitor potency and selectivity, crystal structures of most newly designed compounds complexed to various nitric oxide synthase isoforms have been determined We have discovered a new analog (21), which exhibits not only excellent potency (Ki < 30 nM) in nNOS inhibition but also a significantly low P-glycoprotein and breast-cancer-resistant protein substrate liability as indicated by an efflux ratio of 0.8 in the Caco-2 bidirectional assay.

Two pairs of new optically active nitronyl nitroxides derived from N-Boc-D- or -L-prolinol were described. The synthetic route consists of (1) the synthesis of chiral aryl aldehydes by Mitsunobu reaction, (2) condensation of 2,3-bis(hydroxylamino)-2,3-dimethylbutane with chiral aldehydes to give 1,3-dihydroxyimidazolidines, and (3) finally, subsequent oxidation with aqueous NaIO4 at 0°. These two pairs were specifically designed for further assessing the differences in activity of chiral nitronyl nitroxides and for developing chiral mol. magnetic material by the metal-radical complexes approach.

Neuronal acetylcholine receptors mediate the addictive effects of nicotine and may also be involved in alc. addiction. Varenicline, an approved smoking cessation medication, showed clear efficacy in reducing alc. consumption in heavy-drinking smokers. More recently, sazetidine-A, which selectively desensitizes α4β2 nicotinic receptors, was shown to significantly reduce alc. intake in a rat model. To develop novel therapeutics for treating alc. use disorder, we designed and synthesized novel sazetidine-A analogs containing a Me group at the 2-position of the pyridine ring. In vitro pharmacol. studies revealed that some of the novel compounds showed overall pharmacol. property profiles similar to that of sazetidine-A but exhibited reduced agonist activity across all nicotinic receptor subtypes tested. In rat studies, compound I significantly reduced alc. uptake. More importantly, preliminary results from studies in a ferret model indicate that these novel nAChR ligands have an improved adverse side-effect profile in comparison with that of varenicline.

A series of chiral 2,3-dichlorophenoxy and 1-naphthyloxy alkylamines were synthesized, and their binding affinities towards 5-HT1D and h5-HT1B receptors were evaluated. In the naphthyloxy series, the (R)-prolinol derivative was the most selective 5-HT1D ligand, while (S)-N-methyl-2-(1-naphthyloxy)propan-1-amine showed the highest selectivity for h5-HT1B. Both compounds performed as 5-HT1D agonists in the isolated guinea pig assay and showed higher analgesic activity than both sumatriptan and the achiral analog 20 b (I) in the mouse hot-plate test. Neither ligand displayed any affinity for nicotinic ACh receptors present in mouse brain membranes, thus indicating that their analgesic activity does not arise through interaction with these receptors.
