Disclosed in the present invention is a method for preparing Ticagrelor (I), comprising the following steps: a cyclization reaction of 5-amino-1,4-di-substituted-1,2,3-triazole (II) and dialkyl carbonate (HI), to obtain 9-substituted-2,6-dihydroxy-8-azapurine (IV); chlorination of intermediate (IV), to obtain 9-substituted-2,6-dichloro-8-azapurine (V); an amination reaction of intermediate (V) and trans-(1R,2S)-2-(3,4-difluorophenyl)cyclopropanamine (VI) generates 9-substituted-6-amino-substituted-2-chloro-8-azapurine (VII); and a propanethiolation reaction of intermediate (VII) and propanethiol (VIII), to obtain Ticagrelor (I). The preparation method is simple in process, has a high chemical and chiral purity and provides a new preparation method for industrializing Ticagrelor. In addition, also provided in the present invention are intermediates of Ticagrelor and a preparation method thereof, wherein raw materials of the preparation method are easily available, the conditions thereof are mild, and the yield thereof is high.

Disclosed in the present invention is a compound as represented by formula (IA) or formula (IC) or a pharmaceutically acceptable salt, a stereoisomer, a solvate or a prodrug thereof. The definition of each group in the formula is shown in the description for details. Further disclosed are a pharmaceutical composition containing the compound and the use thereof in the preparation of a drug for preventing and/or treating diseases or conditions related to HPK1 activity.

The invention provides novel imidazol-piperidinyl derivatives of the formula (I) ##STR00001##
in which R.sup.1, R.sup.2, W, X.sup.1, X.sup.2, X.sup.3, X.sup.4 and n have the meanings indicated in formula I, and their manufacture and use for the treatment of hyperproliferative diseases, such as cancer.

The invention provides compositions of novel high penetration compositions (HPC) or high penetration prodrugs (HPP) of 1H-imidazo[4,5-c]quinolin-4-amines and 1H-imidazo[4,5-c]quinolin-4-amine-related compounds, which are capable of crossing biological barriers with high penetration efficiency. The HPPs are capable of being converted to parent active drugs or drug metabolites after crossing the biological barrier and thus can render treatments for the conditions that the parent drugs or metabolites can. Additionally, the HPPs are capable of reaching areas that parent drugs may not be able to access or to render a sufficient concentration at the target areas and therefore render novel treatments. The HPPs can be administered to a subject through various administration routes, e.g., locally delivered to an action site of a condition with a high concentration or systematically administered to a biological subject and enter the general circulation with a faster rate.

The present invention relates to a compound having the structure of Formula I as inhibitor of WNT signal transduction pathways, as well as a composition comprising the compound. Further, the present invention relates to the use of the compound and the method of inhibiting the WNT signal transduction pathways. ##STR00001##
