    • Novel quinazoline derivatives of the formula (1) ##STR1## wherein ring C is a pyrazole ring fused to ring B in two vicinal positions thereof that are not fused with ring A. The novel formula (1) compounds or pyrazolo-quinazoline-ones are structurally related to allopurinol, a well known drug useful in the treatment of gout and are expected to replace or complement allopurinol in the therapeutic use thereof. The generic name Benzoallopurinol is suggested for the novel formula (1) compounds; formula (1) includes angular and linear structures of the interfused rings A, B and C.Two methods for producing the novel formula (1) compounds are disclosed. The first method starts from the indazole structure that includes the interfused rings B and C, and ring A is formed on the indazole moiety. The second method starts from the quinazoline structure that includes interfused rings A and B, and the pyrazole ring C is formed on the benzo moiety (ring B) of the quinazoline structure. Either method may lead to angular or linear benzoallopurinols depending upon the substituents introduced into the starting structure for forming the complemental ring thereon.
    • 新的式(1)化合物或吡唑并喹唑啉衍生物(1)其中环C是与环B的两个相邻位置稠合的环B的吡唑环。 - 酮在结构上与别嘌呤醇有关,别嘌呤醇是用于治疗痛风的众所周知的药物,并且预期在其治疗用途中替代或补充别嘌呤醇。 对于新型配方(1)化合物,建议通用名称苯并嘌呤; 公式(1)包括界面环A,B和C的角度和线性结构。公开了制备新式(1)化合物的两种方法。 第一种方法是从包含界面环B和C的吲唑结构开始,在吲唑部分上形成环A。 第二种方法从包括嵌段环A和B的喹唑啉结构开始,吡唑环C形成在喹唑啉结构的苯并部分(环B)上。 根据引入到起始结构中的取代基来形成其上的互补环,任一方法都可能导致角或线性的苯并嘌呤醇。
