In order to envisage new solutions for complications associated with cardiovascular diseases, including the occlusion of small vessels, a family of random copolymers of poly(butylene -1,4-ciclohexanedicarboxylate) (PBCE), containing Pripol moiety, namely, poly(butylene -1,4-ciclohexaendicarboxylate/Pripol), were successfully synthesized. The copolymers display reduced crystallinity and stiffness compared with PBCE, exhibiting elastic modulus values that are comparable to those of materials previously investigated for similar applications. The stability of the materials under physiological conditions was demonstrated over an extended time. Cytotoxicity was confirmed by a direct contact assay with human umbilical vein endothelial cells (HUVECs), and blood compatibility was established by the absence of any change in the values of activated prothrombin time and activated partial thromboplastin time, in addition to the low adhesion of blood components. The results demonstrated that the ad hoc design is pivotal in regulating solid state and functional properties, thereby facilitating the development of innovative materials for vascular tissue engineering.
为了设想与心血管疾病相关并发症的新解决方案,包括小血管闭塞,成功合成了一族含有普立泊部分的聚(1,4-环己烷二甲酸丁二醇酯)(PBCE)无规共聚物,即聚(1,4-环己烷二甲酸丁二醇酯/普立泊)。与PBCE相比,这些共聚物的结晶度和硬度降低,其弹性模量值与先前研究用于类似应用的材料相当。材料在生理条件下的稳定性在较长时间内得到了证明。通过与人脐静脉内皮细胞(HUVECs)的直接接触试验证实了细胞毒性,并且除了血液成分的低粘附性之外,通过活化凝血酶原时间和活化部分凝血活酶时间的值没有任何变化确定了血液相容性。结果表明,特殊设计在调节固态和功能特性方面至关重要,从而有助于开发用于血管组织工程的创新材料。
