Novel, heterocyclic compounds having at least one ring nitrogen, disclosed side chains and, in some embodiments, an oxygen ortho to the ring nitrogen inhibit inflammatory responses associated with TNF-&agr; and fibroblast proliferation in vivo and in vitro. The compounds of the invention neither appreciably inhibit the activity of cAMP phosphodiesterase nor the hydrolysis of phosphatidic acid, and are neither cytotoxic nor cytostatic. Preferred compounds of the invention are esters. Methods for the use of the novel compounds to inhibit ceramide-mediated intracellular responses in stimuli in vivo (particularly TN-&agr;) are also described. The methods are expected to be of use in reducing inflammatory responses (for example, after angioplasty), in limiting fibrosis (for example, of the liver in cirrhosis), in inhibiting cell senescence, cell apoptosis and UV induced cutaneous immune suppression. Compounds having enhanced water solubility are also described.
新颖的、至少含有一个环状氮的杂环化合物,揭示了侧链,并在某些实施例中,对抗与TNF-α和成纤维细胞增殖有关的炎症反应,无论在体内还是体外。本发明的化合物既不显著抑制cAMP磷酸二酯酶的活性,也不抑制磷脂酸的水解,既不具有细胞毒性,也不具有细胞毒性。本发明的优选化合物是酯类。还描述了使用这些新颖化合物来抑制体内(特别是TN-α)刺激介导的神经酰胺内细胞反应的方法。这些方法预计可用于减少炎症反应(例如在血管成形术后)、限制纤维化(例如在肝硬化中的肝脏)、抑制细胞衰老、细胞凋亡和紫外诱导的皮肤免疫抑制。还描述了具有增强水溶性的化合物。
