通过HTS将8,8-二苯基-2,3,4,8-四氢咪唑并[1,5- a ]嘧啶-6-胺(1)鉴定为BACE1的弱(微摩尔)抑制剂。X射线晶体学研究表明2-氨基咪唑环在BACE1的催化位点与Asp32和Asp228形成关键的H键相互作用。使用基于结构的聚焦库进行的前导优化导致鉴定出具有从S 1到S 3口袋的取代基的低纳摩尔BACE1抑制剂(例如20b)。

The invention relates to new quinoline derivatives of the general Formula I ##STR1## (wherein X stands for hydrogen, halogen or lower alkoxy; n is an integer of 1, 2 or 3; R.sup.1 represents hydrogen and R.sup.2 represents hydroxy-lower alkyl or lower alkoxy-lower alkyl or a group of the general formula IV, ##STR2## wherein Z stands for --O--, --S--, --NH-- or --N(lower alkyl)--; the dotted lines represent optional bonds; and m is 0 or 1; or R.sup.1 and R.sup.2 together with the adjacent nitrogen atom, they are attached to, form a 5- or 6-membered heterocyclic group which may optionally contain a further oxygen, nitrogen or sulfur heteroatom and may be optionally substituted), and pharmaceutically acceptable acid addition salts thereof. The new compounds of the present invention exhibit radiosensitizing effect, make hypoxial cells highly sensitive towards radiation and may be used in radiation therapy.
