We report herein the design and synthesis of a series of orally active, liver-targeted hypoxia-inducible factor prolyl hydroxylase (HIF-PHD) inhibitors for the treatment of anemia. In order to mitigate the concerns for potential systemic side effects, we pursued liver-targeted HIF-PHD inhibitors relying on uptake via organic anion transporting polypeptides (OATPs). Starting from a systemic HIF-PHD inhibitor (1), medicinal chemistry efforts directed toward reducing permeability and, at the same time, maintaining oral absorption led to the synthesis of an array of structurally diverse hydroxypyridone analogues. Compound 28a was chosen for further profiling, because of its excellent in vitro profile and liver selectivity. This compound significantly increased hemoglobin levels in rats, following chronic QD oral administration, and displayed selectivity over systemic effects.

Several 3-acylindoles with high affinity for the CB2 cannabinoid receptor and selectivity over the CB1 receptor have been prepared. A variety of 3-acyl substituents were investigated, and the tetramethylcyclopropyl group was found to lead to high affinity CB2 agonists (5, 16). Substitution at the N1-indole position was then examined. A series of aminoalkylindoles was prepared and several substituted aminoethyl derivatives were active (23-27, 5) at the CB2 receptor.Astudy of N1 nonaromatic side chain variants provided potent agonists at the CB2 receptor (16, 35-41, 44-47, 49-54, and 57-58). Several polar side chains (alcohols, oxazolidinone) were well-tolerated for CB2 receptor activity (41, 50), while others (amide, acid) led to weaker or inactive compounds (55 and 56). N1 aromatic side chains also afforded several high affinity CB2 receptor agonists (61, 63, 65, and 69) but were generally less potent in an in vitro CB2 functional assay than were nonaromatic side chain analogues.

An effective oxidative protocol for the liberation of ketones from SAMP hydrazones employing peroxyselenous acid under aqueous buffered conditions (pH 7) has been developed. The procedure proceeds without epimerization of adjacent stereocenters or dehydration, in representative SAMP alkylation and aldol reaction adducts, respectively.

In a Article，once mentioned of 40191-32-0, Product Details of 40191-32-0

The heterospirocyclic N-methyl-N-phenyl-2H-azirin-3-amines (3-(N- methyl-N-phenylamino)-2H-azirines) 1a-d with a tetrahydro-2H-pyran, tetrahydro-2H-thiopyran, and a N-protected piperidine ring respectively, were synthesized from the corresponding heterocyclic 4-carboxamides 2 by consecutive treatment with lithium diisopropylamide (LDA), diphenyl phosphorochloridate (DPPCl), and sodium azide (Scheme 4). The reaction of these aminoazirines with thiobenzoic acid in CH2Cl2 at room temperature gave the thiocarbamoyl-substituted benzamides 13a-d in high yield. The azirines 1a-d were used as synthons for heterocyclic alpha-amino acids in the preparation of tripeptides of the type Z-Aib-Xaa-Aib-N(Ph)Me (18) by following the protocol of the ‘azirine/ox-azolone method’: treatment of Z- Aib with 1 to give the dipeptide amide 15, followed by selective hydrolysis to the corresponding acid 16 and coupling with the 2,2-dimethyl-2H-azirin-3- amine 17 gave 18, again in high yield (Scheme 5). With some selected examples of 18, the selective deprotection of the amino and the carboxy group, respectively, was demonstrated (Scheme 6). The solid-state conformations of the protected tripeptides 18a-d, as well as that of the corresponding carbocyclic analogue 18e, were determined by X-ray crystallography (Figs. 1- 3 and Tables 1-3). All five tripeprides adopt a beta-turn conformation of type III or III. The solvent dependence of the chemical shifts of the NH resonances (Fig. 6) suggests that there is an intramolecular H-bond between H-N(4) and O(11) in all cases, which is an indication that a relatively rigid beta-turn structure also persists in solution. Surprisingly, the tripeptide acid 20a shows no intramolecular H-bond in the crystalline state (Fig. 7); O(11) is involved in an intermolecular H-bond with the OH group of the carboxy function.

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.Product Details of 40191-32-0, you can also check out more blogs about40191-32-0
