- Synthesis of novel 7-substituted pyrido[2′,3′:4,5]furo[3,2-d] pyrimidin-4-amines and their N-aryl analogues and evaluation of their inhibitory activity against Ser/Thr kinases
-
The efficient synthesis of 7-substituted pyrido[2′,3′:4,5] furo[3,2-d]pyrimidin-4-amines and their N-aryl analogues is described. 3,5-Dibromopyridine was converted into 3-amino-6-bromofuro[3,2-b]pyridine-2- carbonitrile intermediate which was formylated with DMFDMA. Functionalization at position 7 of the tricyclic scaffold was accomplished, before or after cyclisation step, by palladium-catalyzed Suzuki-Miyaura cross-coupling while the pyrimidin-4-amines and N-aryl counterparts were synthesized by microwave-assisted formamide degradation and Dimroth rearrangement, respectively. The final products were evaluated for their potent inhibition of a series of five Ser/Thr kinases (CDK5/p25, CK1δ/ε, CLK1, DYRK1A, GSK3α/β). Compound 35 showed the best inhibitory activity with an IC50 value of 49 nM and proved to be specific to CLK1 among the panel of tested kinases.

- Fine-tuning the selectivity of aldosterone synthase inhibitors: Structure-activity and structure-selectivity insights from studies of heteroaryl substituted 1,2,5,6-tetrahydropyrrolo[3,2,1- ij ]quinolin-4-one derivatives
-
Pyridine substituted 3,4-dihydro-1H-quinolin-2-ones (e.g., 1-3) constitute a class of highly potent and selective inhibitors of aldosterone synthase (CYP11B2), a promising target for the treatment of hyperaldosteronism, congestive heart failure, and myocardial fibrosis. Among these, ethyl-substituted 3 possesses high selectivity against CYP1A2. Rigidification of 3 by incorporation of the ethyl group into a 5- or 6-membered ring affords compounds with a pyrroloquinolinone or pyridoquinolinone molecular scaffold (e.g., 4 and 5). It was found that these molecules are even more potent and selective CYP11B2 inhibitors than their corresponding open-chain analogues. Moreover, pyrroloquinolinone 4 exhibits no inhibition of the six most important hepatic CYP enzymes as well as a bioavailability in the range of the marketed drug fadrozole. The SAR studies disclose that subtle changes in the heterocyclic moiety are responsible for either a strong or a weak inhibition of the highly homologous 11-hydroxylase (CYP11B1). These results are not only important for fine-tuning the selectivity of CYP11B2 inhibitors but also for the development of selective CYP11B1 inhibitors that are of interest for the treatment of Cushing's syndrome and metabolic syndrome.

- An efficient large-scale synthesis of alkyl 5-hydroxy-pyridin- and pyrimidin-2-yl acetate
-
The synthesis of methyl 2-(5-hydroxy-3-methoxypyridin-2-yl)acetate and alkyl 2-(5-hydroxypyrimidin-2-yl)acetate is described. Methodology for an efficient access to 5-hydroxy-pyridin- and pyrimidin-2-yl acetate cores has been developed. Based on the difference in halogen reactivity, 5-bromo-2-chloropyridine and its pyrimidine analogue were functionalized judiciously by SNAr and palladium-catalyzed reactions. The outlined strategy provides a high-yielding route suitable for large-scale synthesis of these compounds as well as paves the way for a potential rapid access to other heterocyclic analogues.

- Structure-activity studies and analgesic efficacy of N-(3-pyridinyl)- bridged bicyclic diamines, exceptionally potent agonists at nicotinic acetylcholine receptors
-
A series of exceptionally potent agonists at neuronal nicotinic acetylcholine receptors (nAChRs) has been investigated. Several N-(3-pyridinyl) derivatives of bridged bicyclic diamines exhibit double-digit-picomolar binding affinities for the α4β2 subtype, placing them with epibatidine among the most potent nAChR ligands described to date. Structure-activity studies have revealed that substitutions, particularly hydrophilic groups in the pyridine 5-position, differentially modulate the agonist activity at ganglionic vs central nAChR subtypes, so that improved subtype selectivity can be demonstrated in vitro. Analgesic efficacy has been achieved across a broad range of pain states, including rodent models of acute thermal nociception, persistent pain, and neuropathic allodynia. Unfortunately, the hydrophilic pyridine substituents that were shown to enhance agonist selectivity for central nAChRs in vitro tend to limit CNS penetration in vivo, so that analgesic efficacy with an improved therapeutic window was not realized with those compounds.

This paper describes a general method for the synthesis of halohydroxypyridines from novel halopyridinylboronic acids and esters recently described by some of us. Halopyridinylboronic acids and esters have been efficiently hydroxydeboronated under mild conditions by employing hydrogen peroxide or meta-chloroperbenzoic acid. These hydroxylations take place regioselectively without other oxidation (N-oxide formation).

We describe the synthesis of a new precursor of 5-IA-85380, specific radiotracer for α4β2 nicotinic acetylcholine receptors. (S)-5-Trimethylstannyl-3-(2-azetidinylmethoxy)pyridine (4) was prepared in six steps and 62% overall yield starting from (S)-2- azetidinecarboxylic acid. The key step of this synthesis is selective release of the amine function without removing the stannyl moiety using trimethylsilyl iodine.

- A comparison of the binding of three series of nicotinic ligands
-
A total of 24 aryl-substituted analogues of nicotine (1a) and two related series of nicotinic ligands, aminomethylpyridines 3 and ether analogues 8, were examined to determine if they bind at α4β2 nACh receptors in a common manner. A modest correlation (r=0.785) was found between the affinities of the nicotine analogues and derivatives of 3, but little correlation (r=0.348) was found with analogues 8. However, a modest correlation (r=0.742) exists between the binding of analogues 3 and 8. It seems that 1-series and 8-series compounds bind differently but that the 3-series compounds share some intermediate binding similarity with both.
