182747-25-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 182747-25-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,2,7,4 and 7 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 182747-25:
(8*1)+(7*8)+(6*2)+(5*7)+(4*4)+(3*7)+(2*2)+(1*5)=157
157 % 10 = 7
So 182747-25-7 is a valid CAS Registry Number.

Design and synthesis of novel hybrid sydnonimine and prodrug useful for glaucomatous optic neuropathy

Acharya, Suchismita,Rogers, Preston,Krishnamoorthy, Raghu R.,Stankowska, Dorota L.,Dias, H.V. Rasika,Yorio, Thomas

, p. 1490 - 1494 (2016)

Synthesis and bioactivity of novel dual acting nitric oxide releasing and reactive oxygen scavenging hybrid compound SA-2 is described. The hybrid molecule SA-2 significantly increased the superoxide dismutase enzyme level and protected the photoreceptor

Convergent syntheses of oral THF 1β-methylcarbapenems

Bitha, Panayota,Li, Zhong,Lin, Yang-I

, p. 643 - 648 (2007/10/03)

Convergent syntheses of oral THF 1β-methylcarbapenems 4 (OCA-983) and 5 starting from M2-phosphate 1 were developed. Reaction of the M2-phosphate 1 with THF thiols containing a requisite prodrug side chain, 9 and 10, gave the desired oral THF 1β-methylcarbapenems 4 and 5, respectively, in 46% and 42% overall yields.

(Acyloxy)alkyl Carbamates as Novel Bioreversible Prodrugs for Amines: Increased Permeation through Biological Membranes

Alexander, Jose,Cargill, Robyn,Michelson, Stuart R.,Schwam, Harvey

, p. 318 - 322 (2007/10/02)

(Acyloxy)alkyl carbamates of the type R1R2N-CO-O-CHR3-OCO-R4 are described as novel bioreversible prodrugs for primary and secondary amines.These were prepared either by a one-step reaction involving nucleophilic attack on p-nitrophenyl α-(acyloxy)alkyl carbonates with displacement of p-nitrophenol or by reaction of α-haloalkyl carbamates with silver or mercury salts of carboxylic acids.Enzymatic hydrolysis of the ester bond in these ester carbamates leads to a cascade reaction resulting in rapid regeneration of the parent amine.Permeability measurements of such nonionic derivatives of atenolol, betaxolol, pindolol, propranolol, and timolol through fuzzy rat skin and rabbit cornea mounted on diffusion cells show that derivatization of the hydrophilic β-blockers results in several-fold increase in permeation through these biological membranes.However, prodrug modification of the lipophilic β-blockers leads to little advantage in permeability characteristics.
