  The conformationally restricted, spatially defined macrocyclic ring system of formula (I) is constituted by three distinct molecular parts: Template A, conformation Modulator B and Bridge C. Macrocycles described by this ring system I are readily manufactured by parallel synthesis or combinatorial chemistry in solution or on solid phase. They are designed to interact with a variety of specific biological target classes, examples being agonistic or antagonistic activity on G-protein coupled receptors (GPCRs), inhibitory activity on enzymes or antimicrobial activity. In particular, these macrocycles show inhibitory activity on endothelin converting enzyme of subtype 1 (ECE-1) and/or the cysteine protease cathepsin S (CatS), and/or act as antagonists of the oxytocin (OT) receptor, thyrotropin-releasing hormone (TRH) receptor and/or leukotriene B4 (LTB4) receptor, and/or as agonists of the bombesin 3 (BB3) receptor, and/or show antimicrobial activity against at least one bacterial strain. Thus they are showing great potential as medicaments for a variety of diseases.

  公式（I）的构象受限、空间定义的大环环系统由三个不同的分子部分组成：模板A、构象调节剂B和桥C。由这种环系统I描述的大环可通过并行合成或溶液中或固相上的组合化学轻松制造。它们被设计用于与各种特定生物靶标类相互作用，例如在G蛋白偶联受体（GPCR）上的激动或拮抗活性，酶的抑制活性或抗菌活性。特别是，这些大环显示对亚型1的内皮素转化酶（ECE-1）和/或半胱氨酸蛋白酶卡特普辛S（CatS）的抑制活性，和/或作为催产素（OT）受体、促甲状腺释放激素（TRH）受体和/或白三烯B4（LTB4）受体的拮抗剂，和/或作为瘤胃素3（BB3）受体的激动剂，和/或对至少一种细菌菌株显示抗菌活性。因此，它们显示出作为各种疾病药物的巨大潜力。
• Photolysis of Triarylmethylphosphonic Acids and Their Esters

  日期：1990.2

  Upon UV-irradiation in an alkaline alcohol solution, some triarylmethylphosphonic acids underwent C–P bond cleavage to give triarylmethanes and alkyl dihydrogenphosphates, while, in an acidic or a neutral alcohol solution, they afforded biaryls. Their dimethyl esters gave also biaryls and dimethyl [alkoxy(aryl)methyl]phosphonates, which were derived from the insertion of (dialkoxyphosphinyl)arylcarbenes

  在碱性醇溶液中紫外线照射后，一些三芳基甲基膦酸发生 C-P 键断裂，得到三芳基甲烷和磷酸二氢烷基酯，而在酸性或中性醇溶液中，它们得到联芳基化合物。它们的二甲酯也产生联芳基和 [烷氧基（芳基）甲基]膦酸二甲酯，它们源自（二烷氧基膦基）芳基卡宾插入醇的 OH 键。卡宾是通过光-α,α-消除膦酸酯的两个芳基而产生的。

  A peptide according to the present invention can perform a function identical or similar to the function of natural CTLA-4 and has an excellent degree of skin penetration due to a small size. The peptide according to the present invention effectively binds to antigen presenting cell surface proteins (CD80 and CD86) to inhibit activity of T cells and thus is capable of inhibiting the expression of inflammatory cytokines (for example, IL-2 and IFN-γ). As a result, a composition comprising the peptide according to the present invention exhibits excellent effects in terms of preventing, treating, or improving Th1-mediated immune diseases. Therefore, the superior activity and stability of the peptide according to the present invention can be useful when applied to medicine, quasi-drugs, and cosmetics.

  根据本发明的肽能够执行与天然CTLA-4相同或类似的功能，并且由于体积小，具有出色的皮肤渗透性。根据本发明的肽有效地结合到抗原呈递细胞表面蛋白（CD80和CD86）上，以抑制T细胞的活性，从而能够抑制炎症细胞因子（例如IL-2和IFN-γ）的表达。因此，包含根据本发明的肽的组合物在预防、治疗或改善Th1介导的免疫性疾病方面表现出优异效果。因此，根据本发明的肽的优越活性和稳定性在应用于药物、准药物和化妆品时可能非常有用。
