Steroid 9α‐Hydroxylation during Testosterone Degradation by Resting Rhodococcus equi Cells
Authors: Kim Yong‐ung , Han Jaehong , Lee Sang Sup , Shimizu Kuniyoshi , Tsutsumi Yuji , Kondo Ryuichiro 
Published: March 2007

AbstractThe conversion pathway of testosterone to androst‐4‐ene‐3,17‐dione and 9α‐hydroxy androstane metabolites, 9α‐hydroxyandrost‐4‐ene‐3,17‐dione and 9α,17β‐dihydroxyandrost‐4‐en‐3‐one was proposed for the ring degradation in steroids by a minimal liquid medium (NMMP)‐dispersed Rhodococcus equi ATCC 14887. The microorganism produced 9α‐hydroxy androstane metabolites from testosterone at high conversion ratio without the addition of ring degradation inhibitory agents. Several NMMP‐based media showed the similar effect on the microbial transformation, in which the respective molar yields of 9α‐hydroxyandrost‐4‐ene‐3,17‐dione and 9α,17β‐dihydroxyandrost‐4‐en‐3‐one were approx. 3 to 47% and approx. 3 to 11%, respectively, whereas nutrient broth, a rich medium, basically showed no accumulation. On the basis of this evidence, magnesium sulfate and casamino acids among the components of NMMP were found to compromise the determinant for the production of the 9α‐hydroxy androstane metabolites without appreciable decomposition of the steroid ring system.

Published: March 2007

AbstractA variety of arylethynylsilanes (Ar‐CCC6H4CC)nSiMe4−n were prepared successfully by reaction of the corresponding chlorosilanes Me4−nSiCln with ArCCC6H4CCM (M=Li, MgBr), which was prepared by treatment of ethynyl(diarylethyne)s ArCCC6H4CCH with BuLi or MeMgBr. The ethynyl(diarylethyne)s were readily prepared in good yields by the double‐elimination method: addition of lithium hexamethyldisilazide to a mixture of ArCH2SO2Ph, TMSCCC6H4CHO, and ClP(O)(OEt)2, followed by desilylation. In the tetrakis(arylethynyl)silanes (ArCCC6H4CC)4Si thus prepared, through‐space conjugation of four triple bonds on the silicon atom emerges as a result of participation of the silicon orbitals in the acetylenic π orbitals. This participation enhances the emissive quantum yields of arylethynylsilanes with an increase in the number of arylethynyl moieties on silicon: quantum yields of emission (ΦF) of 0.72 for (MeOC6H4CCC6H4CC)4Si, 0.53 for (MeOC6H4CCC6H4CC)2SiMe2, and 0.47 for MeO‐C6H4CCC6H4CCSiMe3 were obtained. Although this enhancement effect was also observed in the phenylethynylarylsilane (MeOC6H4CCC6H4)2SiMe2, the bis(arylethynyl)disilane (MeOC6H4CCC6H4CC‐SiMe2)2 exhibited non‐enhanced emission.
Three‐dimensional study of the musculotendinous architecture of supraspinatus and its functional correlations

Published: March 2007

AbstractThe supraspinatus is most frequently involved in shoulder pathology. However, the musculotendinous architecture of the supraspinatus has not been well documented. Therefore, the purpose of this study is to investigate the detailed three‐dimensional architecture of the supraspinatus throughout its volume. Ten male formalin embalmed cadaveric specimens (mean age 61.9 ± 16 years) without any evidence of rotator cuff pathology were used. Three‐dimensional coordinates (x, y, and z) of the tendon and muscle fiber bundles were collected in situ, using serial dissection and digitization. The data was reconstructed into a three‐dimensional model using Maya™. Fiber bundle lengths, pennation angles (PA), muscle volumes, and tendon dimensions for each architecturally distinct area were computed and then analyzed using paired t‐tests and ANOVA (P < 0.05). The supraspinatus was found to consist of anterior and posterior regions, which were each further subdivided into superficial, middle, and deep parts. Mean PA were found to be significantly different between the distinct parts of the anterior region of the muscle. Medial PA was also found be significantly different between the superficial and middle, and superficial and deep parts of the posterior region. These results provide insight into the normal function of the muscle and its possible contribution to the initiation and progression of supraspinatus tendon tears. Clin.

Porous Liquids
Authors: O'Reilly Niamh , Giri Nicola , James Stuart L. 
Published: March 2007

AbstractThe aim of this article is to put forward the novel concept of porous liquids, or, more precisely, liquids with permanent microporosity. In contrast to the small, transient cavities that exist between the molecules of any liquid (here called “extrinsic” porosity), we suggest that a truly microporous liquid could exist if it had empty pores within the molecules of the liquid (“intrinsic” porosity). By using rigid host molecules with restricted access windows, any unwanted occupation of the pores could be prevented (i.e., the pores could be kept empty and available so that the liquid would be genuinely microporous). The liquid could have permanent, well‐defined, empty pores capable of molecular recognition when exposed to other species (e.g., gases etc.). We stress that these phases are not the same as simple solutions of host species, in which any pores would normally be occupied by solvent molecules. In microporous liquids, any solvent molecules, if present, would be deliberately sterically excluded from the host cavities, to leave them readily accessible. Microporous liquids would be of considerable fundamental interest. They could combine properties of microporous solids, such as size‐ and shape‐selective sorption and so forth, with the rapid mass transfer, fluidity and fast kinetics of liquids. Some synthetic approaches to these materials are discussed in this article. Also, whilst the overall concept of microporous liquids is new, literature is described which suggests that some examples have arguably already been reported, even if they have not previously been recognised and characterised in such terms.

New route to enantiopure MαNP acid, a powerful resolution and chiral 1H NMR anisotropy reagent

Published: March 2007

AbstractMαNP acid (±)‐1, 2‐methoxy‐2‐(1‐naphthyl)propionic acid, was enantioresolved by the use of phenylalaninol (S)‐(−)‐4; a diastereomeric mixture of amides formed from acid (±)‐1 and amine (S)‐(−)‐4 was easily separated by fractional recrystallization and/or HPLC on silica gel, yielding amides (R;S)‐(−)‐5a and (S;S)‐(+)‐5b. Their absolute configurations were determined by X‐ray crystallography by reference to the S configuration of the phenylalaninol moiety. Amide (R;S)‐(−)‐5a was converted to oxazoline (R;S)‐(+)‐8a, from which enantiopure MαNP acid (R)‐(−)‐1 was recovered. In a similar way, enantiopure MαNP acid (S)‐(+)‐1 was obtained from amide (S;S)‐(+)‐5b. These reactions provide a new route for the large‐scale preparation of enantiopure MαNP acid, a powerful chiral reagent for the enantioresolution of alcohols and simultaneous determination of their absolute configurations by 1H NMR anisotropy.
