Culture evaluating

Studies on the kinetics of formation of S2F2Q and reviews of appHcable Hterature have been reported (124—126). Other work has concentrated on the use of cell culture evaluation methods for assessing cytotoxic activity of SF decomposition products (127,128). Several laboratories seek to provide methods for accurately determining S2F2Q in operating electrical units (57).

The microbial reduction of 4-benzyloxy-3-methanesulfonylamino-2 -bromoace-tophenone (6) to the corresponding (A)-alcohol (7) was demonstrated by S. paucimobilis SC 16113 (Fig. 6). Among cultures evaluated, Hansenula anamola SC 13833, H. anamola SC 16142, Rhodococcus rhodochrous ATCC 14347, and S. paucimobilis SC 16113, gave desired alcohol (7) in >96% e.e. and >15% reaction yield. S. paucimobilis SC 16113, in the initial screening, catalyzed the efficient conversion of ketone (6) to the desired chiral alcohol (7) in 58% reaction yield and >99.5% e.e. 

So far, most microorganisms and enzymes derived therefrom have been used in the reduction of a single keto group of p-keto or a-keto compounds [68-71], Recently, Patel et al. [72] have demonstrated the stereoselective reduction of 3,5-dioxo-6-(benzyloxy)hexanoic acid, ethyl ester (41), to (3,S, 5R)-dihydroxy-6-(benzyloxy)hexanoic acid, ethyl ester (42a) (Fig. 14). The compound (42a) is a key chiral intermediate required for the chemical synthesis of [4-[4a,6P(E)]]-6-[4,4-bis(4-fluorophenyl)-3-(l-methyl-lH-tetrazol-5-yl)-l,3-butadienyl]-tetrahydro-4-hydroxy-2H-pyran-2-one, compound R-( + )-(43), a new anticholesterol drug that acts by inhibition of HMG CoA reductase [73], Among various microbial cultures evaluated for the stereoselective reduction of diketone (41), cell suspensions of Aci-... 

Schoeters et al. (1995) evaluated the hematopoietic and osteogenic toxicity of benzene, phenol, hydroquinone, and catechol in vitro using murine bone marrow cultures. Evaluation of toxicity to 3T3-fibroblasts was included to determine specific toxicity to marrow cells. Benzene and phenol showed little effect. However, hydroquinone inhibited proliferation of 3T3 cells and marrow precursor cells, and calcification of bone cells, although it was more specific for marrow cells. Catechol inhibited all cells, and showed no specificity.

Enantioselective Hydrolysis of Racemic 1- 2, 3 -Dihydro Benzofb]Furan-4 -yl -1,2-Oxirane. Epoxide hydrolase catalyzes the enantioselective hydrolysis of an epoxide to the corresponding enantiomerically enriched diol and unreacted epoxide (22,23). The (5)-epoxide (12) is a key intermediate in the synthesis of a number of prospective drug candidates (24). The enantiospecific hydrolysis of the racemic 1- 2, 3 -dihydro benzo[b]furan-4 -yl -l,2-oxirane (13) to the corresponding (R)-diol (14) and unreacted -epoxide (12) (Fig. 4A) was demonstrated by Goswami et aL (25). Among cultures evaluated, two Aspergillus niger strains (SC 16310, SC 16311)... 

The establishment of evaluation index system of safety culture is an arduous and complex task, including the establishment of safety culture evaluation index, determination of evaluation method, measurement of evaluation results and so on. At present, domestic research in this area is still not perfect.

Finally, the pHEMA-based functional hydrogel-CP composites developed here are subjects of extensive in vitro and in vivo evaluations. Our preliminary in vitro cell culture evaluations have shown that osteoblasts can adhere and proliferate over the functional hydrogel-CP composites containing up to 10% anionic residues. We are also interested to learn how the underlying anionic mineral binding motifs of the composite would direct new mineral deposition by osteoblasts once the amorphous (or nanocrystalline) CP layer is resorbed by osteoclasts upon implantation.
