Yulan Chen et al.
Nature chemistry, 4(7), 559-562 (2012-06-22)
Nature uses mechanochemical transduction processes to achieve diverse and vital functions, such as hearing, cellular adhesion and gating of ion channels. One fascinating example of biological mechanotransduction is the emission of light on mechanical stimulation. However, molecular-level transduction of force

Dispiro N-Boc-protected 1,2,4-trioxane 2 was synthesised via Mo(acac)(2) catalysed perhydrolysis of N-Boc spirooxirane followed by condensation of the resulting beta-hydroperoxy alcohol 10 with 2-adamantanone. N-Boc 1,2,4-trioxane 2 was converted to the amine 1,2,4-trioxane hydrochloride salt 3 which was subsequently used

Biochemistry, 39(46), 14219-14231 (2000-11-23)
Photodissociation of (CO)P-450(cam)(substrate) complexes was found to trigger a conformational relaxation process that interferes with ligand rebinding at temperatures as low as 140 K even though the protein conformational substates (CS(1)) remain frozen. To analyze the rebinding and relaxation kinetics

Reaction of 1,1-dilithio-1-sila-2,3,4,5-tetraphenylsilole with 2-adamantanone produces a 5-silafulvene. This represents a new method for synthesis of silenes, leading to the first example of a silapentafulvene.

We report that the oxygen sensitivity of some Fe(II) complexes with tripodal ligands can be used, with benefit, in the oxidation of cyclohexane under mild conditions. Depending on the solvent, two very different reaction pathways are involved, which share the

The Journal of organic chemistry, 75(12), 4274-4279 (2010-05-26)
Deprotonation of 2-adamantanone (1) in the gas phase affords the corresponding beta-enolate anion. This ion was independently prepared by the fluoride-induced desilylation of 4-trimethylsilyl-2-adamantanone, and its reactivity and thermodynamic properties were measured (DeltaH degrees(acid) = 394.7 +/- 1.4, EA =

Archives of biochemistry and biophysics, 228(2), 493-502 (1984-02-01)
Three alicyclic compounds (D-camphor, adamantanone, adamantane) were found to be hydroxylated by the cytochrome P-450 isoenzymes P-450cam and P-450LM2. With P-450cam as the catalyst only one product was formed from each of the substrates: 5-exohydroxycamphor, 5-hydroxyadamantanone, and 1-adamantanol. With P-450LM2

An adamantanone derivative that is an original modulator of redox processes in the cytochrome P-450 system can serve as an effective remedy against obliterating angiopathy of lower extremities.

The crystal structures of cytochrome P-450CAM complexed with the alternative substrates norcamphor and adamantanone have been refined at 2.0-A resolution and compared with the native, camphor-bound form of the enzyme. Norcamphor lacks the 8-, 9-, and 10-methyl groups of camphor.

Il Farmaco; edizione scientifica, 35(5), 430-440 (1980-05-01)
The synthesis of (+/-)-1-(adamantan-2-yl)-2-propanamine (VI), its N,N-dimethyl derivative (VII) and other amines (VIII), (IX) and (X), starting from 2-adamantanone, is described. Some of these amines showed antiparkinson activity in mice.

Intact cells of (+/-)camphor-grown Pseudomonas putida, ATCC17453(CAM), have been shown to oxidize readily the monoketone derivative of cage hydrocarbon adamantane, forming oxygenated products indicative of both biological Baeyer-Villiger and hydroxylation reactions. Formed products were identified as 4-oxahomoadamantan-5-one, 5-hydroxyadamantan-2-one and 1-hydroxy-4-oxahomoadamantan-5-one.

The repair of sublethal radiation damage (SLD) in Chinese hamster (V79) cells was investigated as a function of temperature in the presence and absence of the membrane lipid perturbers, butylated hydroxytoluene (BHT) or adamantanone, which decrease the viscosity of the

EPR/ENDOR studies have been carried out on oxyferrous cytochrome P450cam one-electron cryoreduced by gamma-irradiation at 77 K in the absence of substrate and in the presence of a variety of substrates including its native hydroxylation substrate, camphor (a), and the

The Baeyer-Villiger oxidation, first reported more than 100 years ago, has evolved into a versatile reaction widely used to convert ketones-readily available building blocks in organic chemistry-into more complex and valuable esters and lactones. Catalytic versions of the Baeyer-Villiger oxidation
