865451-01-0 Usage

Preparation

Obtained by reaction of acetyl chloride with 4-chloro-3- fluorophenol in the presence of aluminium chloride in toluene, first at 40° for 1 h, then at 80° for 3 h (61%).

Check Digit Verification of cas no

The CAS Registry Mumber 865451-01-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,5,4,5 and 1 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 865451-01:
(8*8)+(7*6)+(6*5)+(5*4)+(4*5)+(3*1)+(2*0)+(1*1)=180
180 % 10 = 0
So 865451-01-0 is a valid CAS Registry Number.

A medicinal chemistry effort focused on identifying a structurally diverse candidate for phosphoinositide 3-kinase delta (PI3Kδ) led to the discovery of clinical candidate INCB050465 (20, parsaclisib). The unique structure of 20 contains a pyrazolopyrimidine hinge-binder in place of a purine motif that is present in other PI3Kδinhibitors, such as idelalisib (1), duvelisib (2), and INCB040093 (3, dezapelisib). Parsaclisib (20) is a potent and highly selective inhibitor of PI3Kδwith drug-like ADME properties that exhibited an excellent in vivo profile as demonstrated through pharmacokinetic studies in rats, dogs, and monkeys and through pharmacodynamic and efficacy studies in a mouse Pfeiffer xenograft model.
