[6-Chloro-9-(4-methoxy-3,5-dimethylpyridin-2-ylmethyl)-9H-purin-2-yl]amine

ChEBI: A member of the class of 2-aminopurines that is 2-aminopurine which is substituted by a chlorine at position 6 and by a (4-methoxy-3,5-dimethylpyridin-2-yl)methyl group at position 9.

BIIB021 is a member of the class of 2-aminopurines that is 2-aminopurine which is substituted by a chlorine at position 6 and by a (4-methoxy-3,5-dimethylpyridin-2-yl)methyl group at position 9. It has a role as a Hsp90 inhibitor and an antineoplastic agent. It is a member of pyridines, a member of 2-aminopurines, an organochlorine compound and an aromatic ether.|BIIB021 has been investigated for the treatment of Tumors and Lymphoma.|Hsp90 Inhibitor BIIB021 is an orally active inhibitor of heat shock protein 90 (HSP90) with potential antineoplastic activity. HSP90, a chaperon protein upregulated in a variety of tumor cells, regulates the folding and degradation of many oncogenic signaling proteins. HSP90 inhibitor BIIB021 specifically blocks active HSP90, thereby inhibiting its chaperon function and promoting the degradation of oncogenic signaling proteins involved in tumor cell proliferation and survival. As a result, CNF2024 has the potential to inhibit the growth of a wide range of cancer cells in both solid tumors and blood-based cancers.

Weigh respectively 2-amino-6-chloropurine 10mmol, anhydrous potassium carbonate 12mmol, the amount of 25mL DMSO was added to a 50mL round bottom flask, the oil bath was heated to 48 ° C, stirring reaction 30min;11 mmol of 2-chloromethyl-3, 5-dimethylpyridine hydrochloride was weighed and added to the above reaction solution in 3 portions at intervals of 30 minutes.After reacting at 48 °C for 10 h, the temperature was set to 22 °C and stirred for 2 h. After the reaction was completed, the reaction solution was filtered and the filtrate was retained.The volume ratio of water: isopropyl alcohol = 1:1 mixed solution was added to the filtrate, until the solution became turbid to stop dropping, and the solution was placed in a refrigerator to stand still overnight. The filter residue was parent molecule BIIB021. 6-Chloro-9-[(4-methoxy-3, 5-dimethyl-2-pyridyl)methyl]-9H-purin-2-amine (BIIB021):Light yellow solid; Yield: 77percent;Weigh the 2-amino-6-chloropurine 10mmol, anhydrous potassium carbonate 12mmol, measure 25mL DMSO into a 50mL round bottom flask, and raise the temperature in the oil bath to 48°C.The reaction was stirred for 30 min; 11 mmol of 2-chloromethyl-3, 5-dimethylpyridine hydrochloride was weighed and added to the above reaction solution in 3 portions at intervals of 30 min. After reaction at 48 °C for 10 h, the temperature was set to 22 ° C and stirred for 2 h.After the reaction is completed, the reaction solution is suction-filtered, and the filtrate is retained; a mixed solution with a volume ratio of water:isopropanol = 1:1 is added to the filtrate, until the solution becomes turbid, and the solution is added dropwise. The solution is left in the refrigerator at rest overnight, and the filter is filtered.

BIIB 021 an orally available, fully synthetic small-molecule inhibitor of the heat shock protein Hsp90. Studies show that BIIB 021 adminisitration led to degradation of Hsp90 client proteins measured in tumor tissue and resulted in the inhibition of tumor growth in several human tumor xenograft models.
