77-53-2 Usage
Description
Cedrol is a sesquiterpene alcohol found in conifers mainly of the genera Cupressus, Juniperus, and Cedrus. It has been found to possess significant anticancer activity against glioblastoma in vitro and in vivo via cell growth inhibition, ROS generation, and DNA damage.1 Cedrol also displayed synergistic effects with temozolomide against glioblastoma in vitro and in vivo via reduced expression of drug resistance proteins.1,2 Cedrol inhibited the growth of human renal adenocarcinoma and amelanotic melanoma cells3 and induced autophagy and apoptosis in A549 non-small cell lung carcinoma cells4.
Chemical Properties
Colorless crystals; cedarwood odor. soluble in 11 parts of 95% alcohol. Combustible.
Occurrence
Found in the wood of several conifers, particularly cypresses and cedars, including Cedrus atlantica, Cupressus sempervirens, Juniperus virginiana (Fenarolfs Handbook of Flavor Ingredients, 1971).
Uses
Different sources of media describe the Uses of 77-53-2 differently. You can refer to the following data:
1. acaricide, enhances skin ECM production
2. (+)-Cedrol can be used as a starting material for the preparation of cedryl acetate by acetylation using acetic anhydride in the presence of an acid catalyst. It can also be incorporated as a precursor for the total synthesis of rare illicium sesquiterpene (+)-pseudoanisatin via selective C-H bond functionalization.
Preparation
From cedarwood by fractional distillation followed by recrystallization from suitable solvents of appropriate solid fractions.
Definition
A tertiary terpene alcohol.
General Description
(+)-Cedrol is a crystalline hydrated product of α-cedrene, which is a sesquiterpene found in cedar-wood oil. It can be used as a fragrance ingredient in cosmetics, shampoos, and soaps as well as in non-cosmetic products such as cleaners and detergents. (±) Cedrol can be synthesized by intramolecular Diels-Alder reaction of alkyl cyclopentadiene.
Purification Methods
Purify cedrol by recrystallisation from aqueous MeOH. It is estimated colorimetrically with H3PO4 in EtOH followed by vanillin and HCl [Hayward & Seymour Anal Chem 20 572 1948]. The 3,5-dinitrobenzoyl derivative has m 92-93o. [Stork & Clarke J Am Chem Soc 83 3114 1961, Beilstein 6 III 424.]

Check Digit Verification of cas no
The CAS Registry Mumber 77-53-2 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 7 and 7 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 77-53:
(4*7)+(3*7)+(2*5)+(1*3)=62
62 % 10 = 2
So 77-53-2 is a valid CAS Registry Number.

Characterization of a sesquiterpene cyclase from the glandular trichomes of Leucosceptrum canum for sole production of cedrol in Escherichia coli and Nicotiana benthamiana

Cedrol is an extremely versatile sesquiterpene alcohol that was approved by the Food and Drug Administration of the United States as a flavoring agent or adjuvant and has been commonly used as a flavoring ingredient in cosmetics, foods and medicine. Furthermore, cedrol possesses a wide range of pharmacological properties including sedative, anti-inflammatory and cytotoxic activities. Commercial production of cedrol relies on fractional distillation of cedar wood oils, followed by recrystallization, and little has been reported about its biosynthesis and aspects of synthetic biology. Here, we report the cloning and functional characterization of a cedrol synthase gene (Lc-CedS) from the transcriptome of the glandular trichomes of a woody Lamiaceae plant Leucosceptrum canum. The recombinant Lc-CedS protein catalyzed the in vitro conversion of farnesyl diphosphate into the single product cedrol, suggesting that Lc-CedS is a high-fidelity terpene synthase. Co-expression of Lc-CedS, a farnesyl diphosphate synthase gene and seven genes of the mevalonate (MVA) pathway responsible for converting acetyl-CoA into farnesyl diphosphate in Escherichia coli afforded 363 μg/L cedrol as the sole product under shaking flask conditions. Transient expression of Lc-CedS in Nicotiana benthamiana also resulted in a single product cedrol with a production level of 3.6 μg/g fresh weight. The sole production of cedrol by introducing of Lc-CedS in engineered E. coli and N. benthamiana suggests now alternative production systems using synthetic biology approaches that would better address sufficient supply of cedrol.

Processes for the preparation of 8,14-cedranoxide are disclosed, according to which 8,14-cedrane diol is prepared by reducing 8,14-cedranolide by treatment with the aid of diisobutyl-aluminum hydride followed by acid hydrolysis, or 8,14-cedrane diol is cyclized with dimethyl sulfoxide.
