    • The synthesis and use of bifunctional molecules to improve the topical and transdermal delivery efficiency of various types of therapeutic agents or agents designed to promote the transdermal delivery of those therapeutic agents either into the skin tissue or into the systemic circulation. Three major classes of molecules are covalently joined as bifunctional substances; chemical vasodilators, passive dermal penetration enhancers and therapeutic or diagnostic drugs. Chemical vasodilators may be delivered into the skin to increasing the blood flow in a tissue that has compromised circulation or they may be used as part of a delivery vehicle to promote the delivery of the drug. Passive dermal penetration enhancers are those chemicals that promote the passive penetration of drugs and other chemicals through the stratum corneum and epidermis of the skin tissue. Drugs and diagnostic agents are the third group of chemicals that are candidates for the linkage of molecules.
    • 双功能分子的合成和使用以改善各种类型治疗剂或试剂的局部和透皮递送效率,所述治疗剂或试剂旨在促进将这些治疗剂透皮递送至皮肤组织或进入体循环。 三大类分子共价连接成双功能物质; 化学血管扩张剂,被动皮肤渗透增强剂和治疗或诊断药物。 化学血管扩张剂可以被递送到皮肤中以增加已经损害循环的组织中的血液流动,或者它们可以用作递送载体的一部分以促进药物的递送。 被动皮肤渗透增强剂是促进药物和其他化学物质通过角质层和皮肤组织表皮的被动穿透的化学物质。 药物和诊断剂是作为分子连接的候选物的第三组化学品。
