  Design, Synthesis, and Biological Evaluation of Symmetrically and Unsymmetrically Substituted Methoctramine-Related Polyamines as Muscular Nicotinic Receptor Noncompetitive Antagonists

  摘要：

  The universal template approach to drug design foresees that a polyamine can be modified in such a way to recognize any neurotransmitter receptor. Thus, hybrids of polymethylene tetraamines and philanthotoxins, exemplified by methoctramine (1) and PhTX-343 (2), respectively, were synthesized to produce novel inhibitors of muscular nicotinic acetylcholine receptors. Polyamines 3-25 were synthesized and their biological profiles were evaluated at frog rectus abdominis muscle nicotinic receptors and guinea pig left atria (M-2) and ileum longitudinal muscle (M-3) muscarinic acetylcholine receptors. All of the compounds, like prototypes 1 and 2, were noncompetitive antagonists of nicotinic receptors while being, like 1, competitive antagonists at,muscarinic M-2 and M-3 receptor subtypes. interestingly, polyamines bearing a low number of methylenes between the nitrogen atoms, as in 3, 6, and 7, displayed a biological profile similar to that of 2: a noncompetitive antagonism at nicotinic receptors in the 7-25 mu M range while not showing any antagonism for muscarinic receptors up to 10 mu M. increasing the number of methylenes separating these nitrogen atoms in methoctramine related tetraamines resulted in a significant improvement; in potency at nicotinic receptors. The most potent tetraamine was 19, bearing a 12 methylene spacer between the nitrogen atoms, which was 12-fold and 250-fold more potent than prototypes 1 and 2, respectively. Tetraamines 9-11, bearing a rather rigid spacer between the nitrogen atoms instead of the very flexible polymethylene chain, displayed a profile similar to that of 1 at nicotinic receptors, whereas a significant decrease in potency was observed at muscarinic M-2 receptors. This finding may have relevance in understanding the mode of interaction with these receptors. Similarly, the constrained analogue 12 of methoctramine showed a decrease in potency at nicotinic and muscarinic M-2 receptors, revealing that the tricyclic system, which incorporates the 2-methoxybenzylamine moiety of 1, does not represent a good pharmacophore for activity at these sites. A most intriguing finding was the observation that the photolabile tetraamine 22 was more potent than methoctramine at nicotinic receptors and, what is more important, it inhibited a closed stale of the receptor.

  Chemotherapeutic agents combining several active groups within a single molecule can modulate multiple cellular pathways and, thus, exhibit higher efficacy than single-target drugs. In this study, six new hybrid compounds combining tamoxifen (TAM) or ferrocifen (FcTAM) structural motifs with suberoylanilide hydroxamic acid (SAHA) were synthesised and evaluated. Antiproliferative activity was first explored in cancer cell lines. Combining FcTAM and SAHA structural motifs to form the unprecedented FcTAM–SAHA hybrid molecule led to an increased cytotoxicity (IC50 = 0.7 μM) in triple-negative MDA-MB-231 breast cancer cells when compared to FcTAM or SAHA alone (IC50 = 2.6 μM and 3.6 μM, respectively), while the organic hybrid analogue TAM–SAHA was far less cytotoxic (IC50 = 8.6 μM). In hormone-dependent MCF-7 breast cancer cells, FcTAM–SAHA was more active (IC50 = 2.0 μM) than FcTAM (IC50 = 4.4 μM) and TAM–SAHA (IC50 > 10 μM), but less toxic than SAHA (IC50 = 1.0 μM). Surprisingly, FcTAM–PSA, an N1-phenylsuberamide derivative, also possessed strong antiproliferative activity (IC50 = 0.5 μM and 1.8 μM in MDA-MB-231 and MCF-7 cells, respectively). Subsequent biochemical studies indicate that estrogen receptor alpha (ERα) and histone deacetylases (HDAC) are not the main targets of the hybrid compounds for their antiproliferative effect. Interestingly, both organometallic compounds were able to induce p21waf1/cip1 gene expression in MCF-7 breast cancer cells in accordance with their antiproliferative activity.

  将多个活性基团结合于单一分子中的化疗药物能够调控多条细胞信号通路，因此其疗效高于单一靶点药物。在本研究中，我们合成并评估了6种新型混合化合物，它们结合了他莫昔芬（TAM）或铁西他莫（FcTAM）结构基团与辛二酰苯胺异羟肟酸（SAHA）。首先在癌细胞系中探索它们的抗增殖活性。将FcTAM与SAHA结构基团结合起来形成前所未有的FcTAM-SAHA混合分子，与单独的FcTAM或SAHA相比（分别为IC50 = 2.6 μM和3.6 μM），在三阴性乳腺癌细胞MDA-MB-231中显示出增加的细胞毒性（IC50 = 0.7 μM），而有机混合类似物TAM-SAHA的细胞毒性则低得多（IC50 = 8.6 μM）。在激素依赖性乳腺癌细胞MCF-7中，FcTAM-SAHA的活性比FcTAM（IC50 = 4.4 μM）和TAM-SAHA（IC50 > 10 μM）更高（IC50 = 2.0 μM），但毒性比SAHA（IC50 = 1.0 μM）低。令人惊讶的是，N1-苯基辛二酰胺衍生物FcTAM-PSA也显示出强大的抗增殖活性（在MDA-MB-231和MCF-7细胞中分别为IC50 = 0.5 μM和1.8 μM）。后续的生化研究表明，雌激素受体α（ERα）和组蛋白去乙酰化酶（HDAC）并不是这些混合化合物抗增殖作用的主要靶点。有趣的是，这两种有机金属化合物都能根据其抗增殖活性诱导MCF-7乳腺癌细胞中的p21waf1/cip1基因表达。
