  2‘-C-Methyl Analogues of Selective Adenosine Receptor Agonists:  Synthesis and Binding Studies

  摘要：

  2'-C-Methyl analogues of selective adenosine receptor agonists such as (R)-PIA, CPA, CCPA, NECA, and IB-MECA were synthesized in order to further investigate the subdomain that binds the ribose moiety. Binding affinities of these new compounds at A(1) and A(2A) receptors in bovine brain membranes and at A(3) in rat testis membranes were determined and compared. It was found that the 2'-C-methyl modification resulted in a decrease of the affinity, particularly at A(2A) and A(3) receptors. When such modification was combined with N-6-substitutions with groups which induce high potency and selectivity at Al receptors, the high affinity was retained and the selectivity was increased. Thus, 2-chloro-2'-C-methyl-N-6-cyclopentyladenosine (2'-Me-CCPA), which displayed a K-i value of 1.8 nM at A(1) receptors, was selective for A(1) vs A(2A) and A(3) receptors by 2166- and 2777-fold, respectively, resulting in one of the most potent and A(1)-selective agonists so far known. In functional assay, this compound inhibited forskolin-stimulated adenylyl cyclase activity with an IC50 value of 13.1 nM, acting as a full agonist.

  A series of 5'-carbamoyl and 5'-thionocarbamoyl derivatives of 2'-C-methyl analogues of the A, adenosine receptor (AIAR) full agonists N-6-cyclopentyladenosine (CPA), 2-chloro-N-6-cyclopentyladenosine (CCPA), N-6-[3-(R)-tetrahydrofuranyl]adenosine (tecadenoson), and 2-chloro analogue (2-Cl-tecadenoson) was synthesized and evaluated for their affinity for adenosine receptor subtypes from bovine, porcine, and human species. In the N-6-cyclopentylamino series, the 5'-substituted derivatives showed a reduced affinity at the bovine A(1)AR compared to the parent compounds; however, the selectivity for A(1) versus A(2A) receptor was retained or increased. The corresponding N-6-3-(R)-tetrahydrofuranylamino analogues displayed a very low affinity toward the bovine AIAR. The 5'-methylthionocarbamoyl derivative of 2'-Me-CCPA showed the best affinity at porcine AIAR with a K-i value of 13 nM. At human AR subtypes tecadenoson derivatives showed 2.3- to 5-fold lower affinity at AIAR and very low affinity at the other subtypes (A(2A), A(2B), and A(3) compared to the corresponding N-6-cyclopentyl analogues. The 5'-carbamoyl and 5'-thionocarbamoyl derivatives of 2'-Me-CCPA 3, 4, 7 and tecadenoson derivative 12 were found to be partial A, agonists at the porcine receptor. Docking studies explained the lower affinity of N-6-3-(R)-tetrahydrofuranyl-substituted compounds at bovine AIAR compared to that of N-6-cyclopentyl analogues, showing that the oxygen of the tetrahydrofuranyl ring establishes unfavorable electrostatic interactions with the CO oxygen of Asn254. The low binding affinity of the 2'-C-methyl-N-6-3-(R)-tetrahydrofuranyl adenosine analogues at human AIAR may be ascribed to the presence of unfavorable interactions between the hydrophilic tetrahydrofuranyl ring and the surrounding hydrophobic residues Leu250 (TM6) and Ile274 (TM7).
