109069-76-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 109069-76-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,0,6 and 9 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 109069-76:
(8*1)+(7*0)+(6*9)+(5*0)+(4*6)+(3*9)+(2*7)+(1*6)=133
133 % 10 = 3
So 109069-76-3 is a valid CAS Registry Number.

Synthesis and biological evaluation of novel analogues of the pan class i phosphatidylinositol 3-kinase (PI3K) inhibitor 2-(Difluoromethyl)-1-[4,6-di(4- morpholinyl)-1,3,5-triazin-2-yl]-1 H -benzimidazole (ZSTK474)

experimental part, p. 7105 - 7126 (2011/12/04)

A structure-activity relationship (SAR) study of the pan class I PI 3-kinase inhibitor 2-(difluoromethyl)-1-[4,6-di(4-morpholinyl)-1,3,5-triazin-2- yl]-1H-benzimidazole (ZSTK474) identified substitution at the 4 and 6 positions of the benzimidazole ring as having significant effects on the potency of substituted derivatives. The 6-amino-4-methoxy analogue displayed a greater than 1000-fold potency enhancement over the corresponding 6-aza-4-methoxy analogue against all three class Ia PI 3-kinase enzymes (p110α, p110β, and p110δ) and also displayed significant potency against two mutant forms of the p110α isoform (H1047R and E545K). This compound was also evaluated in vivo against a U87MG human glioblastoma tumor xenograft model in Rag1 -/- mice, and at a dose of 50 mg/kg given by ip injection at a qd ?- 10 dosing schedule it dramatically reduced cancer growth by 81% compared to untreated controls.

Alkaloids from Annonaceae 93. First synthesis of a meta-disubstituted aporphine

Roblot, F.,Hocquemiller, R.,Cave, A.

, p. 258 - 267 (2007/10/02)

The synthesis of a new aporphinoid alkaloid, substituted on the 9 and 11 positions, is reported.An unexpected reactivity has been observed for several intermediates.It has been attributed to the position of the methoxy groups with regard to the nitro group.
