The present invention relates to triazolo[4,3-a]quinazoline-5-ones and 5-thiones of Formula I and Formula II, whereby I and II are position isomers of group R on nitrogen 3 or 4. Optionally, the invention also relates to the racemic forms, isomers and pharmaceutically acceptable salts thereof. The invention further relates to a method for the production thereof and to compositions containing said derivatives. The compounds act as inhibitors of phosphodiesterase IV (PDE-4) and, as such, have utility in treating asthma, chronic bronchitis, acutte pulmonary attack, atopic dermatitis, pulmonary hypertension, pulmonary insufficiency, cardiac insufficiency, psoriasis, inflammatory conditions of the digestive system such as haemorrhagic rectocolitis and Crohn's disease, acute respiratory distress syndrome, acute pancreatitis, benign hypertrophy of the prostate, rheumatoid arthritis, multiple sclerosis, depression, ischaemia-induced neuronal damage, partial cerebral ischaemia, and cancer such as malignant tumor and chronic lymphoid leukemia.
本发明涉及式I和式II的三唑并[4,3-a]喹唑啉-5-酮和5-硫酮,其中I和II是氮原子3或4上的基团R的位置异构体。选项地,本发明还涉及其消旋形式、异构体和药学上可接受的盐。本发明还涉及一种其生产方法和含有所述衍生物的组合物。这些化合物作为磷酸二酯酶IV(PDE-4)的抑制剂,因此在治疗哮喘、慢性支气管炎、急性肺部疾病、特应性皮炎、肺动脉高压、肺功能不全、心功能不全、牛皮癣、消化系统的炎症性疾病如出血性直肠结肠炎和克罗恩病、急性呼吸窘迫综合征、急性胰腺炎、前列腺良性增生、类风湿性关节炎、多发性硬化、抑郁症、缺血诱导的神经损伤、部分脑缺血以及恶性肿瘤和慢性淋巴细胞白血病等癌症治疗中具有用途。
