产品介绍
Theophylline (1,3-Dimethylxanthine) 是有效的磷酸二酯酶 (PDE) 抑制剂，腺苷受体拮抗剂，和组蛋白脱乙酰酶 (HDAC) 活化剂。Theophylline (1,3-Dimethylxanthine) 抑制 PDE3 活性，放松气道平滑肌。Theophylline (1,3-Dimethylxanthine) 通过增加 IL-10 和抑制 NF-κ B进入细胞核而具有抗炎活性。Theophylline (1,3-Dimethylxanthine) 诱发细胞凋亡 (apoptosis)。Theophylline (1,3-Dimethylxanthine) 可用于哮喘和慢性阻塞性肺疾病 (COPD) 的研究。

茶碱是临床医学检验技士/技师/主管技师考试复习需要了解的生化检验知识，医学|教育网搜集整理了相关内容与考生分享，希望给予大家帮助！ 茶碱通常制成氨茶碱等水溶性较高的盐类供药用，但在体内均解离出茶碱发挥作用，故不论何种制剂，TDM检测对象均为茶碱。下面以氨茶碱为代表讨论。 （一）药效学及血药浓度参考范围 茶碱可抑制细胞内磷酸二酯酶，使β肾上腺素受体激动产生的胞内信使物质cAMP分解代谢受阻而堆积，出现类似β肾上腺素受体激动样作用。临床上主要用于预防和治疗支气管
C7 H8 N4 O2 ，是茶中所含的白色不定形的结晶状生物碱，为可可碱（ theobromine）的异构体。作用和结构都类似咖啡碱。具有松弛平滑肌、兴奋心脏肌以及利尿的作用。副作用有恶心、呕吐和眩晕等。
