906670-24-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 906670-24-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,6,6,7 and 0 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 906670-24:
(8*9)+(7*0)+(6*6)+(5*6)+(4*7)+(3*0)+(2*2)+(1*4)=174
174 % 10 = 4
So 906670-24-4 is a valid CAS Registry Number.

Phosphotyrosine prodrugs: design, synthesis and anti-STAT3 activity of ISS-610 aryloxy triester phosphoramidate prodrugs

Miccoli, Ageo,Dhiani, Binar A.,Mehellou, Youcef

, p. 200 - 208 (2019)

Unmasked phohate groups of phosphotyrosine-containing molecules carry two negative charges at physiological pH, which compromise their (passive) cellular uptake. Also, these phosphate groups are often cleaved off by phosphatases. Together, these ultimatel

FLOXURIDINE SYNTHESIS

-

, (2019/04/11)

The present invention relates to a process for the preparation of floxuridine, said process comprising reacting a compound of Formula la with a compound of Formula lla in the presence of an acid Al to provide a compound of Formula Ilia in substantially diastereomerically pure form. Floxuridine may be useful as an anti-cancer drug. Floxuridine may also be useful in the preparation of other anti-cancer drugs, e.g. NUC-3373.

Targeting GNE Myopathy: A Dual Prodrug Approach for the Delivery of N-Acetylmannosamine 6-Phosphate

ProTides comprise an important class of prodrugs currently marketed and developed as antiviral and anticancer therapies. The ProTide technology employs phosphate masking groups capable of providing more favorable druglike properties and an intracellular activation mechanism for enzyme-mediated release of a nucleoside monophosphate. Herein, we describe the application of phosphoramidate chemistry to 1,3,4-O-acetylated N-acetylmannosamine (Ac3ManNAc) to deliver ManNAc-6-phosphate (ManNAc-6-P), a critical intermediate in sialic acid biosynthesis. Sialic acid deficiency is a hallmark of GNE myopathy, a rare congenital disorder of glycosylation (CDG) caused by mutations in GNE that limit the production of ManNAc-6-P. Synthetic methods were developed to provide a library of Ac3ManNAc-6-phosphoramidates that were evaluated in a series of studies for their potential as a treatment for GNE myopathy. Prodrug 12b showed rapid activation in a carboxylesterase (CPY) enzymatic assay and favorable ADME properties, while also being more effective than ManNAc at increasing sialic acid levels in GNE-deficient cell lines. These results provide a potential platform to address substrate deficiencies in GNE myopathy and other CDGs.

Application of ProTide technology to gemcitabine: A successful approach to overcome the key cancer resistance mechanisms leads to a new agent (NUC-1031) in clinical development

Slusarczyk, Magdalena,Lopez, Monica Huerta,Balzarini, Jan,Mason, Malcolm,Jiang, Wen G.,Blagden, Sarah,Thompson, Emely,Ghazaly, Essam,McGuigan, Christopher

, p. 1531 - 1542 (2014/03/21)

Gemcitabine is a nucleoside analogue commonly used in cancer therapy but with limited efficacy due to a high susceptibility to cancer cell resistance. The addition of a phosphoramidate motif to the gemcitabine can protect it against many of the key cancer resistance mechanisms. We have synthesized a series of gemcitabine phosphoramidate prodrugs and screened for cytostatic activity in a range of different tumor cell lines. Among the synthesized compounds, one in particular (NUC-1031, 6f) was shown to be potent in vitro. Importantly, compared with gemcitabine, 6f activation was significantly less dependent on deoxycytidine kinase and on nucleoside transporters, and it was resistant to cytidine deaminase-mediated degradation. Moreover, 6f showed a significant reduction in tumor volumes in vivo in pancreatic cancer xenografts. The ProTide 6f is now in clinical development with encouraging efficacy signals in a Phase I/II study, which strongly supports the ProTide approach to generate promising new anticancer agents.

Synthesis and biological evaluation of pyrimidine nucleoside monophosphate prodrugs targeted against influenza virus

Meneghesso, Silvia,Vanderlinden, Evelien,Stevaert, Annelies,McGuigan, Christopher,Balzarini, Jan,Naesens, Lieve

, p. 35 - 43 (2012/07/28)

Uridine-based nucleoside analogues have often been found to have relatively poor antiviral activity. Enzymatic assays, evaluating inhibition of influenza virus RNA polymerase, revealed that some uridine triphosphate derivatives displayed inhibitory activity on UTP incorporation into viral RNA. Here we report the synthesis, antiviral activity and enzymatic evaluation of novel ProTides designed to deliver the activated (monophosphorylated) uridine analogues inside the influenza virus-infected cells. After evaluation of the activation profile we identified two ProTides with moderate antiviral activity in MDCK cells (23a, EC99=49±38μM and 23b, EC99≥81μM) while the corresponding nucleoside analogue (2'-fluoro-2'-deoxyuridine) was inactive. Thus, at least in these cases the poor antiviral activity of the uridine analogues may be ascribed to poor phosphorylation.
