  Synthesis of a chemical compound having the formula A-B-C that may serve for applications such as drug delivery where A is a chemiluminescent, moiety, B is a photochromic moiety, and C is a biologically active moiety where A-B-C may serve as a prodrug. Novel synthetic methods of the present invention to form the prodrug comprised the steps of (1) forming a benzophenone, (2) forming a diaryl ethylene, (3) attaching a phthalimide moiety to at least one of the aryl groups of the ethylene to form a phthalimide-ethylene conjugate, (4) condensing two ethylene-phthalimide conjugates to form a phthalimide-pentadiene conjugate, (5) converting the phthalimide to the phthalhydrazide by reaction with hydrazine to form a carrier compound according to the present invention, and (6) reacting the carrier compound with an nucleophilic moiety of the drug to form the corresponding prodrug. Alternatively the carrier can be prepared by using the halo-substituted diaryl ethylene to make the corresponding cationic leuco dye-like compound with known methods. The cationic compound then is protected by reacting with a nucleophile and coupled with the aminophathalimide by palladium-catalyzed amination to form the protected phthalimide-pentadiene conjugate. The latter is refluxed with hydrazine to convert its phthalimide to the phthalhydrazide and acidified to give the carrier. An additional aspect of the present invention relates to the use of these compounds as antiviral agents for the treatment of viral infections such as HIV and as anticancer agents for the treatment of cancers such as bowel, lung, and breast cancer.

  Renal-selective prodrugs are described which are preferentially converted in the kidney to compounds capable of inhibiting synthesis of catecholamine-type neurotransmitters involved in renal sympathetic nerve activity. The prodrugs described herein are derived from inhibitor compounds capable of inhibiting one or more of the enzymes involved in catecholamine synthesis, such compounds being classifiable as tyrosine hydroxylase inhibitors, or as dopa-decarboxylase inhibitors, or as dopamine-&bgr;-hydroxylase inhibitors. These inhibitor compounds are linked to a chemical moiety, such as a glutamic acid derivative, by a cleavable bond which is recognized selectively by enzymes located predominantly in the kidney. The liberated inhibitor compound is then available in the kidney to inhibit one or more of the enzymes involved in catecholamine synthesis. Inhibition of renal catecholamine synthesis can suppress heightened renal nerve activity associated with sodium-retention related disorders such as hypertension. Conjugates of particular interest are glutamyl derivatives of dopamine-&bgr;-hydroxylase inhibitors, of which N-acetyl-&ggr;-glutamyl fusaric acid hydrazide (shown below) is preferred. 1

  本文描述了一种肾选择性的前药，其在肾脏中优先转化为能够抑制参与肾交感神经活动的儿茶酚型神经递质合成的化合物。本文所描述的前药来源于能够抑制儿茶酚合成中的一个或多个酶的抑制剂化合物，这些化合物可分类为酪氨酸羟化酶抑制剂，多巴脱羧酶抑制剂或多巴胺-&bgr;-羟化酶抑制剂。这些抑制剂化合物通过可被肾脏中大量存在的酶选择性识别的可裂解键与化学基团（如谷氨酸衍生物）连接。释放的抑制剂化合物然后可在肾脏中用于抑制儿茶酚合成中的一个或多个酶。抑制肾脏儿茶酚合成可抑制与钠潴留相关的疾病（如高血压）相关的增强肾脏神经活动。特别感兴趣的共轭物是多巴胺-&bgr;-羟化酶抑制剂的谷氨酰衍生物，其中N-乙酰-&ggr;-谷氨酰富萨酸肼（如下图所示）是首选。1
