138-52-3 Usage

Description

D(-)-Salicin is a traditional medicine which has been known to exhibit anti-inflammation and other therapeutic activities, it can inhibit the LPS-induced inflammation in RAW264.7 cells and mouse models.

Chemical Properties

white crystals or powder

Uses

Different sources of media describe the Uses of 138-52-3 differently. You can refer to the following data:
1. analgesic, antipyretic
2. H1 antihistamine (nonsedating)
3. Standard substrate in evaluating enzyme Preparations contg b-glucosidase: Weidenhagen, Z. Ver. Zucker-Ind. 79, 591 (1929).
4. D-(-)-Salicin has been used:to study its in vitro anticoagulant and antiplatelet activitiesas a standard in high performance liquid chromatography method (HPLC) for quantitation of salicin from willow plantas a tastant in taste threshold assayas a constituent of nutrient agar-salicin medium for selective isolation of Lactobacillus paracasei

Definition

ChEBI: An aryl beta-D-glucoside that is the beta-D-glucoside of the phenolic hydroxy group of salicyl alcohol.

General Description

Salicin is a non-phenolic glucosidic compound extracted from meadowsweet (Filipendula ulmaria L). It is majorly used as a substitute for quinine. Salicin can be used as a therapeutic for patients suffering from rheumatic fever. Salicin acts a metabolic precursor for salicylic acid. It is a novel phytochemical that exhibits immunological cross functions in plants and humans. Salicin facilitates growth and reproduction in plants. In addition, It also protects plants against biotic and abiotic stress.

Biochem/physiol Actions

D-(?)-Salicin exerts anti-rheumatism and anti-inflammatory activities. It inhibits lipopolysaccharide (LPS) induced inflammation in in vitro and in vivo studies. It regulates different signaling pathways such as nuclear factor kappa B (NF-κB) and mitogen-activated protein kinase (MAPK). It also regulates cytokines concentration such as tumor necrosis factor-alpha(TNF-α), interleukin-1β, interleukin-6, and interleukin-10.

Purification Methods

Crystallise D(-)-salicin from EtOAc, EtOH or water and sublime it at 190-195o/12mm. [Armour et al. J Chem Soc 412 1961, IR: Pearl & Darling J Org Chem 24 731 1959, Beilstein 17 III/IV 2986, 17/7 V 113.]

Check Digit Verification of cas no

The CAS Registry Mumber 138-52-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,3 and 8 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 138-52:
(5*1)+(4*3)+(3*8)+(2*5)+(1*2)=53
53 % 10 = 3
So 138-52-3 is a valid CAS Registry Number.

Isolation of Salicin Derivatives from Homalium cochinchinensis and Their Antiviral Activities

Ishikawa, Tsutomu,Nishigaya, Kaori,Takami, Kazuko,Uchikoshi, Hide,Chen, Ih-Sheng,Tsai, Ian-Lih

, p. 659 - 663 (2004)

The chemical constituents of Homalium cochinchinensis were examined. From the root bark, in addition to the previously reported cochinolide and its β-glucopyranoside, cochinchiside A (1) and tremulacinol (4) were isolated together with three known compounds [benzoic acid, tremulacin (2), and tremuloidin (3)]. From the leaves, cochinchiside B (5) was isolated as new compound. The structures of the new compounds (1, 4, 5) were determined by spectroscopic and/or chemical methods. Antiviral testing of compounds 2-5 against HSV-1 and HSV-2 showed that tremulacin (2) and cochinchiside B (5) were weakly active. Tremulacin (2) was also weakly active against HIV-1.

Adopting the ‘remote activation concept’ toward stereocontrolled glycoside synthesis with minimal use of protection groups, a general synthesis of phenolic 1,2-cis glycopyranosides is reported, as exemplified by aryl α-d-galacto-, α-d-gluco- and 2-azido α-d-glucopyranosides among others using glycosyl donors bearing an anomeric (3-bromo-2-pyridyloxy) group and catalyzed by methyl triflate.

The glucosylation of some coumarin and flavone derivatives on incubation with the hairy roots of morning glory (Pharbitis nil) was previously reported. We further studied the biotransformation of benzaldehyde- and acetophenone-type derivatives. Vanillin a
