Check Digit Verification of cas no

The CAS Registry Mumber 69942-12-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,9,4 and 2 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 69942-12:
(7*6)+(6*9)+(5*9)+(4*4)+(3*2)+(2*1)+(1*2)=167
167 % 10 = 7
So 69942-12-7 is a valid CAS Registry Number.

Identification of fonofos metabolites in Latuca sativa, Beta vulgaris, and Triticum aestivum by packed capillary flow fast atom bombardment tandem mass spectrometry.

The metabolism of fonofos, a thiophosphonate insecticide, was investigated in mature lettuce (Latuca sativa), beet (Beta vulgaris), and wheat (Triticum aestivum). Six new metabolites were identified by LC-MS and LC-MS-MS analysis using fast atom bombardment (FAB) and packed capillary LC columns with application of the on-column focusing technique. These methods provided the sensitivity required to identify unknown metabolites that were present in the mature plants at only 20-230 ppb. Structural elucidation was facilitated by use of fonofos labeled with both carbon-14 and carbon-13 in the phenyl ring. In all three plants fonofos was converted to a glucose conjugate of thiophenoxylactic acid. Oxidation of the glucose conjugate gave isomeric sulfoxides in all species examined. Thiophenoxylactic acid was found esterified to malonic acid in lettuce. In beets, S-phenylcysteine was found as its malonic acid amide. A second metabolite unique to beets was N-(malonyl)-[2[(ethoxyethylphosphinothionyl)oxy]phenyl]cysteine. This novel structure was confirmed by synthesis.

Discovery of 3-Quinazolin-4(3 H)-on-3-yl-2, N-dimethylpropanamides as Orally Active and Selective PI3Kα Inhibitors

Phosphoinositide 3-kinases (PI3Ks) mediate a series of events related to cell growth, proliferation, survival, and differentiation. Overexpression of PI3Ks can lead to the dysregulation of cell homeostasis and cause tumorigenesis. In this study, rationally designed compounds were investigated as PI3Kα-selective inhibitors. Our efforts culminated in the discovery of a series of quinazolin-4(3H)-one derivatives with 2-substituted-N-methylpropanamide substitutions as PI3Kα-selective inhibitors. The best compound, 10, has PI3Kα enzymatic and cellular IC50 values of 1.8 and 12.1 nM, respectively. It exhibits biochemical selectivities for PI3Kα over PI3Kβ/δ/γof 150/7.72/7.67-fold and cellular selectivities of 115/15.1/>826-fold, respectively. Compound 10 is 59% orally bioavailable with a dose-normalized AUC of 3090 nM. These effects translated into in vivo conditions, as 10 significantly time- and dose-dependently inhibited phosphorylation of Akt in BT-474 subcutaneous xenograft mice and inhibited tumor growth.

Synthesis method of benserazide hydrochloride

-

Paragraph 0126- 0129, (2019/12/11)

The invention relates to a synthesis method of benserazide hydrochloride. According to the synthesis method, serine methyl ester hydrochloride is taken as the primary raw material, at first, amino protection reactions are carried out; and then amine-ester exchange reactions, condensation reactions, reduction reactions, and de-protection reactions are performed to obtain high purity benserazide hydrochloride. The synthesis method has the advantages that the raw materials are cheap and easily available, the operation is convenient, the product purity and yield of each step are high, and thus thesynthesis method is suitable for industrial production.
