Check Digit Verification of cas no

The CAS Registry Mumber 4937-87-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,3 and 7 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 4937-87:
(6*4)+(5*9)+(4*3)+(3*7)+(2*8)+(1*7)=125
125 % 10 = 5
So 4937-87-5 is a valid CAS Registry Number.

Discovery of Hydroxyamidine Derivatives as Highly Potent, Selective Indoleamine-2,3-dioxygenase 1 Inhibitors

Jin, Fangfang,Hu, Qiyue,Fei, Hongbo,Lv, Hejun,Wang, Shenglan,Gui, Bin,Zhang, Junzhen,Tu, Wangyang,Zhang, Yun,Zhang, Lei,Wan, Hong,Zhang, Limin,Hu, Bin,Yang, Fanglong,Bai, Chang,He, Feng,Zhang, Lianshan,Tao, Weikang

In this study, a series of novel hydroxyamidine derivatives were identified as potent and selective IDO1 inhibitors by structure-based drug design. Among them, compounds 13-15 and 18 exhibited favorable enzymatic and cellular activities. Compound 18 showed improved bioavailability in mouse, rat, and dog (F% = 44%, 58.8%, 102.1%, respectively). With reasonable in vivo pharmacokinetic properties, compound 18 was further evaluated in a transgenic MC38 xenograft mouse model. The combination of compound 18 with PD-1 monoclonal antibody showed a synergistic antitumor effect. These data indicated that compound 18 as a potential cancer immunotherapy agent should warrant further investigation.

Water-Assisted Nitrile Oxide Cycloadditions: Synthesis of Isoxazoles and Stereoselective Syntheses of Isoxazolines and 1,2,4-Oxadiazoles

Kesornpun, Chatchai,Aree, Thammarat,Mahidol, Chulabhorn,Ruchirawat, Somsak,Kittakoop, Prasat

Conventional methods generate nitrile oxides from oxime halides in organic solvents under basic conditions. However, the present work revealed that water-assisted generation of nitrile oxides proceeds under mild acidic conditions (pH 4-5). Cycloadditions of nitrile oxides with alkynes and alkenes easily occurred in water without using catalysts, thus yielding isoxazoles and isoxazolines, respectively, with excellent stereoselectivity toward five- and six-membered cyclic alkenes. A double stereoselective cycloaddition of two units of a nitrile oxide with cyclohexene was also achieved, thus yielding 1,2,4-oxadiazole derivatives having a unique hybrid isoxazoline-oxadiazole skeleton. Enantiomerically pure isoxazolines were prepared from monoterpenes with a ring strain. In one case, the isoxazoline with a butterfly-like structure was simply prepared, and it might be used as a ligand in asymmetric catalysis.

New pyrido[2,1-b]benzothiazoles 2a,b, 3, 2-aminoquinoline 4, coumarin 5, cyclohexane 6a,b, and 2-(1,3-benzothiazol-2-yl) methylidene 7 derivatives have been prepared via the reaction of 2-cyanomethyl-1,3-benzothiazole 1 with ,-unsaturated nitriles, α-chloro ethyl acetoacetate, 2-amino benzaldehyde, 5-chlorosalicylaldehyde, α,β-unsaturated ketone, and 2-aminobenzothiol hydrochloride. 2-Thiazole derivatives 9a,b were prepared from compound 1, which was converted to thioamide derivative 8 by reaction with HCl and thioacetamide, and cyclization of this thioamide with α-halogenated ketone gave 9a,b. Reaction of compound 1 and ethylacetate to afford ketonitrile 10. Treatment of 10 with hydrazine hydrate afforded aminopyrazole derivative 11. Substituted 4-aminothiophene 13 has been synthesized by reaction of compound 1 with p-chlorophenyl isothiocyanate. The resulting product 12 was then alkylated with phenacylbromide. Phenyl-2-yl-carbonylhydroximoyl-chloride 15 was prepared by treatment of the corresponding sulfonium bromide with sodium nitrite and hydrochloric acid in dioxane. Compound 15 reacted with α-(1,3- benzothiazol-2-yl) cinnamonitrile 14 afforded the isoxazole derivatives 16. Reaction of coumarin derivative 5 with anthranilamide, pyrimidine diamine, thiosemicarbazide, acetylacetone, and hydrazine hydrate yielded quinazoline-2-one 17, purine 18, triazole 19, 2-acetyl naphthalene-2-one 20, and N-aminoquinoline-2-one 21 derivatives.

Synthesis of hydroximoyl chlorides from aldoximes and benzyltrimethylammonium tetrachloroiodate (BTMA ICl4)

Kanemasa, Shuji,Matsuda, Haruhiko,Kamimura, Akio,Kakinami, Takaaki

, p. 1057 - 1064 (2007/10/03)

Benzyltrimethylammonium tetrachloroiodate (BTMA ICl4) acts as a convenient reagent to convert aldoximes to hydroximoyl chlorides by a simple procedure. When an aldoxime is treated with BTMA ICl4 in dichloromethane, the suspension of BTMA ICl4 shortly disappears as the reaction proceeds. The resulting BTMA ICl2 can be precipitated out by adding diethyl ether. Not only stable aromatic and heteroaromatic hydroximoyl chlorides can be isolated by this method but also rather unstable aliphatic hydroximoyl chlorides can be generated in situ. 1,3-Dipole trapping with a dipolarophile is performed in one flask and in some cases the chlorination is successfully performed in the presence of dipolarophile and triethylamine. Effect of MS 4A has been examined. (C) 2000 Elsevier Science Ltd.
