  This invention relates to novel homotopic prodrugs and medicaments and methods for their preparation, testing and use. In one embodiment, the homotopic prodrug has the general formula wherein is a biologically-active moiety comprising a carboxylic acid functional group, and R b is a homotopically-symmetrical alcohol bonded to the biologically-active moiety through the carboxylic acid functional group to form an ester linkage, as well as optical isomers, enantiomers, pharmaceutically acceptable salts, biohydrolyzable amides, esters, and imides thereof and combinations thereof.

  这项发明涉及新型同位素前药、药物以及其制备、测试和使用方法。在一个实施例中，同位素前药具有一般公式 其中 是包含羧酸官能团的生物活性基团，而 R b 是通过羧酸官能团与生物活性基团形成酯键的同位对称醇，以及其光学异构体、对映异构体、药用可接受盐、生物水解酰胺、酯、亚酰胺及其组合物。

  The present invention relates generally to ophthamological drugs. More specifically, the inventon relates to a method of modifying (derivatizing) ophthamological drugs so as to increase their penetration through the cornea. The invention also relates to drugs modified (derivatized) in accordance with the instant method and to the use of same in treating conditions associated with elevated intraocular pressure, particularly, glaucoma.

  本发明一般涉及眼科药物。更具体地，本发明涉及一种修改（衍生化）眼科药物的方法，以增加它们通过角膜的渗透性。本发明还涉及根据本方法修改（衍生化）的药物，以及将其用于治疗与眼内压升高相关的疾病，特别是青光眼。

  A golf ball comprises a core, an outer cover layer, and, optionally, an intermediate layer disposed between the core and the outer cover layer. The outer cover layer may comprise a polyurethane or polyurea composition. At least one portion of the golf ball comprises a composition that enhances physical properties and/or performance characteristics (e.g., coefficient of restitution) of the golf ball. Preferably, the coefficient of restitution of the core is 0.8 or greater.

  高尔夫球由内核、外覆盖层和可选的中间层组成，外覆盖层可以包括聚氨酯或聚脲组成。高尔夫球的至少一部分包含一种增强物理特性和/或性能特征（例如反弹系数）的组合物。最好，内核的反弹系数为0.8或更高。
