  Prevention and rescue of cardiac dysfunction by methanocarba adenosine monophosphonate derivatives

  摘要：

  越来越多的证据表明，嘌呤能信号传导在心脏疾病中发挥着治疗作用。此前，在心力衰竭动物模型中证实了全身灌注 MRS2339（2-Cl-腺苷单磷酸的带电甲氧羰基衍生物）的疗效。现在，我们对以下假设进行了验证：一种不带电的腺嘌呤核苷膦酸盐，适合作为具有抗水解磷酸分子的口服药物，可在梗死后缺血或压力过载诱导的小鼠心力衰竭模型中预防心功能不全的发生。在缺血或压力过载诱导的心力衰竭开始时，口服二酯掩蔽的非带电膦酸盐 MRS2978 能有效预防心功能不全，并能改善左心室（LV）分数缩短率。MRS2925是一种带电、未掩蔽的MRS2978类似物，皮下注射可预防心功能不全，但口服则无效。口服或全身给药时，MRS2978（而非 MRS2925）也能挽救缺血和压力过载心力衰竭模型中已建立的心功能障碍。二酯掩蔽磷酸盐 MRS4074 在预防功能障碍的发生以及挽救压力过载引起的心衰和缺血性心衰方面具有很高的疗效。在大鼠试验中，MRS2978 的口服生物利用度高（57-75%），在体内可产生次要代谢产物 MRS2925。这些数据表明腺嘌呤核苷膦酸盐对收缩性心力衰竭具有新的治疗作用。

  P2X receptor activation protects in heart failure models. MRS2339 3, a 2-chloro-AMP derivative containing a (N)-methanocarba (bicyclo[3.1.0]hexane) system, activates this cardioprotective channel. Michaelis-Arbuzov and Wittig reactions provided phosphonate analogues of 3, expected to be stable in vivo due to the C P bond. After chronic administration via a mini-osmotic pump (Alzet), some analogues significantly increased intact heart contractile function in calsequestrin-overexpressing mice (genetic model of heart failure) compared to vehicle-infused mice (all inactive at the vasodilatory P2Y(1) receptor). Two phosphonates, (1'S,2'R,3',5,4'R,5'S)-4'-(6-amino-2-chloropurin-9-y1)-2',3'-(dihydroxy)-1'-(phosphonomethylene)-bicyclo[3.1.0]hexane, 4 (MRS2775), and its homologue 9 (MRS2935), both 5'-saturated, containing a 2-Cl substitution, improved echocardiography-derived fractional shortening (20.25% and 19.26%, respectively, versus 13.78% in controls), while unsaturated 5'-extended phosphonates, all 2-H analogues, and a CH3-phosphonate were inactive. Thus, chronic administration of nucleotidase-resistant phosphonates conferred a beneficial effect, likely via cardiac P2X receptor activation. Thus, we have greatly expanded the range of carbocyclic nucleotide analogues that represent potential candidates for the treatment of heart failure.

  Phosphonate and phosphinate N-methanocarba derivatives of AMP including their prodrug analogs are described. MRS2339, a 2-chloro-AMP derivative containing a (N)-methanocarba(bicyclo[3.1.0]hexane) ring system in place of ribose, activates P2X receptors, ligand-gated ion channels. Phosphonate analogues of MRS2339 were synthesized using Michaelis-Arbuzov and Wittig reactions, based on the expectation of increased half-life in vivo due to the stability of the C—P bond. When administered to calsequestrin-overexpressing mice (a genetic model of heart failure) via a mini-osmotic pump (Alzet), some analogues significantly increased intact heart contractile function in vivo, as assessed by echocardiography-derived fractional shortening (FS) as compared to vehicle-infused mice. The range of carbocyclic nucleotide analogues for treatment of heart failure has been expanded.
