Provided are mucolytic agents represented by formula (la)-(ld) where the structural variables Rl, R2, R5 and R6 are as defined herein. Also provided are a variety of methods of treatment which take advantage of the mucolytic properties of the compounds represented by formula (la)-(ld). One object of the present invention relates to a method to increase the liquefaction of mucus in a patient with excessive mucus or mucus with increased viscoelastic, cohesive, or adhesive properties. The method includes the step of contacting the mucus of a patient with abnormal or excessive mucus with a composition comprising a mucolytic compound containing a dithiol group to decrease mucus viscoelasticity through the reduction of mucin disulfide bonds.
提供的是由公式(la)-(ld)表示的粘液溶解剂,其中结构变量R1、R2、R5和R6如本文所述定义。还提供了利用由公式(la)-(ld)表示的化合物粘液溶解性质的各种治疗方法。本发明的一个对象涉及一种方法,用于增加具有过多粘液或粘液粘弹性、内聚力或粘附性增加的患者的粘液液化。该方法包括将异常或过多粘液的患者粘液与包含含有二
硫醇基团的粘液溶解化合物的组合物接触,通过减少粘蛋白二
硫键来降低粘液粘弹性。
