Abstract
AIM Presently, N-hydroxy-N'-phenyloctanediamide (vorinostat) which is an effective histone deacetylase inhibitor, is being synthesized chemically. Hence, present study aims to develop an eco-friendly approach for the synthesis of vorinostat from N'-phenyloctanediamide through biotransformation. METHODS AND RESULTS Using the amidase of Bacillus smithii IIIMB2907 in time course conversion and organic solvent compatibility, maximum bioconversion was observed at 12 h of reaction time and in presence of ethanol, respectively. Potassium phosphate buffer of pH 7·0 supported maximum bioconversion of N'-phenyloctanediamide (10 mmol l-1 ) into N-hydroxy-N'- phenyloctanediamide at 40°C. Bench scale study was successfully carried out with 83% yield of purified vorinostat. CONCLUSION In this study, an eco-friendly approach for the biotransformation of N'-phenyloctanediamide into vorinostat was developed by using cell free extract of thermophilic strain B. smithii IIIMB2907. SIGNIFICANCE AND IMPACT OF THE STUDY Microbial amidase has achieved remarkable attention in the field of biotransformation for the green synthesis of hydroxamic acids. Utilization of amidase from B. smithii IIIMB2907, specifically in the synthesis of vorinostat drug is a foremost attempt in the development a novel process and can also be employed in the synthesis of its derivatives as well.

Bioprocess development for nicotinic acid hydroxamate synthesis by acyltransferase activity of Bacillus smithii strain IITR6b2. ACTA ACUST UNITED AC 2013; 40:937-46.

Abstract
Abstract
In this work, acyltransferase activity of a new bacterial isolate Bacillus smithii strain IITR6b2 was utilized for the synthesis of nicotinic acid hydroxamate (NAH), a heterocyclic class of hydroxamic acid. NAH is an important pyridine derivative and has found its role as bioligand, urease inhibitor, antityrosinase, antioxidant, antimetastatic, and vasodilating agents. Amidase having acyltransferase activity with nicotinamide is suitable for nicotinic acid hydroxamate production. However, amidase can also simultaneously hydrolyze nicotinamide and nicotinic acid hydroxamate to nicotinic acid. Nicotinic acid is an undesirable by-product and thus any biocatalytic process involving amidase for nicotinic acid hydroxamate production needs to have high ratios of acyltransferase to amide hydrolase and acyltransferase to nicotinic acid hydroxamate hydrolase activity. Isolate Bacillus smithii strain IITR6b2 was found to have 28- and 12.3-fold higher acyltransferase to amide and hydroxamic acid hydrolase activities, respectively. This higher ratio resulted in a limited undesirable by-product, nicotinic acid (NA) synthesis. The optimal substrate/co-substrate ratio, pH, temperature, incubation time, and resting cells concentration were 200/250 mM, 7, 30 °C, 40 min, and 0.7 mgDCW ml−1, respectively, and 94.5 % molar conversion of nicotinamide to nicotinic acid hydroxamate was achieved under these reaction conditions. To avoid substrate inhibition effect, a fed-batch process based on the optimized parameters with two feedings of substrates (200/200 mM) at 40-min intervals was developed and a molar conversion yield of 89.4 % with the productivity of 52.9 g h−1 gDCW −1 was achieved at laboratory scale. Finally, 6.4 g of powder containing 58.5 % (w/w) nicotinic acid hydroxamate was recovered after lyophilization and further purification resulted in 95 % pure product.

Appl Microbiol Biotechnol 2013; 98:1595-607. [PMID: 23695777 DOI: 10.1007/s00253-013-4968-9] [Citation(s) in RCA: 25] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2013] [Revised: 04/23/2013] [Accepted: 04/29/2013] [Indexed: 11/24/2022]
Abstract
The nitrilase from Pseudomonas fluorescens EBC191 was modified by introducing random mutations via error-prone PCR techniques in order to obtain nitrilase variants, which form increased amounts of mandeloamide from racemic mandelonitrile. A screening system was established and experimentally optimized, which allowed the screening of nitrilase variants with the intended phenotype. This system was based on the simultaneous expression of nitrilase variants and the mandeloamide converting amidase from Rhodococcus rhodochrous MP50 in recombinant Escherichia coli cells. The formation of increased amounts of mandeloamide from mandelonitrile by the nitrilase variants was detected after the addition of hydroxylamine and ferric iron ions by taking advantage of the acyltransferase activity of the amidase, which resulted in the formation of coloured iron(III)-hydroxamate complexes from mandeloamide. The system was applied for the screening of libraries of nitrilase variants and 30 enzyme variants identified, which formed increased amounts of mandeloamide from racemic mandelonitrile. The increase in amide formation was quantified by high-performance liquid chromatography and the genes encoding the relevant nitrilase variants sequenced. Thus, different types of mutations were identified. One group of mutants carried different deletions at the carboxy-terminus. The other types of variants carried amino acid exchanges in positions that had not been related previously to an increased amide formation. Finally, a nitrilase variant was created by combining two independently obtained point mutations. This enzyme variant demonstrated a true nitrile hydratase activity as it formed mandeloamide and mandelic acid in a ratio of about 19:1 from racemic mandelonitrile.

Abstract
The thermal properties of three matrix metalloproteinase (MMP) inhibitors were investigated using a variety of instrumental methods. Differential scanning calorimetry revealed highly exothermic processes for all compounds above 200°C, and thermogravimetric analysis resulted in significant step-wise weight losses at the temperatures corresponding to the exothermic transitions. Hot stage microscopy observations for several compounds showed evolution of gas bubbles from crystals at temperatures that correlated with the exotherms. Thermal decomposition involving the hydroxamic acid functional group was suspected and further evaluated using various analytical techniques including reversed-phase HPLC, LC-MS-MS, TGA-FTIR and NMR. The mechanism proposed in the thermal decomposition involves a Lossen Rearrangement to form a dimeric species containing a urea linkage.

Abstract
Carbonyldiimidazole (CDI) was found to mediate the Lossen rearrangement of various hydroxamic acids to isocyanates. This process is experimentally simple and mild, with imidazole and CO(2) being the sole stoichiometric byproduct. Significant for large-scale application, the method avoids the use of hazardous reagents and thus represents a green alternative to standard processing conditions for the Curtius and Hofmann rearrangements.

Abstract
A novel enantioselective amidase screening system was developed and proved to be efficient and accurate. This screening system employed acyl transfer activity of amidase in the presence of hydroxylamine, leading to the formation of hydroxamic acids, followed by spectrophotometric quantification of hydroxamic acid/iron(III) complexes. The enantioselectivities of amidase were evaluated by employing (R, S)-2, 2-dimethyl cyclopropanecarboxamide (1), (S)-2, 2-dimethyl cyclopropanecarboxamide and their mixture as substrates concurrently under the same conditions. To prove the accuracy of the screening system, enantioselectivity of acyl transfer reaction (E (T)) and that of hydrolytic reaction (E (H)) was compared. With this method, we obtained eight microorganism strains with enantioselective amidase from 523 isolates, two of which showed R-stereospecific avtivity for (R, S)-1.

Abstract
The gene for an enantioselective amidase was cloned from Rhodococcus erythropolis MP50, which utilizes various aromatic nitriles via a nitrile hydratase/amidase system as nitrogen sources. The gene encoded a protein of 525 amino acids which corresponded to a protein with a molecular mass of 55.5 kDa. The deduced complete amino acid sequence showed homology to other enantioselective amidases from different bacterial genera. The nucleotide sequence approximately 2.5 kb upstream and downstream of the amidase gene was determined, but no indications for a structural coupling of the amidase gene with the genes for a nitrile hydratase were found. The amidase gene was carried by an approximately 40-kb circular plasmid in R. erythropolis MP50. The amidase was heterologously expressed in Escherichia coli and shown to hydrolyze 2-phenylpropionamide, alpha-chlorophenylacetamide, and alpha-methoxyphenylacetamide with high enantioselectivity; mandeloamide and 2-methyl-3-phenylpropionamide were also converted, but only with reduced enantioselectivity. The recombinant E. coli strain which synthesized the amidase gene was shown to grow with organic amides as nitrogen sources. A comparison of the amidase activities observed with whole cells or cell extracts of the recombinant E. coli strain suggested that the transport of the amides into the cells becomes the rate-limiting step for amide hydrolysis in recombinant E. coli strains.

Abstract
A kinetic resolution process for the production of chiral amines was developed using an enzyme-membrane reactor (EMR) and a hollow-fiber membrane contactor with (S)-specific omega-transaminases (omega-TA) from Vibrio fluvialis JS17 and Bacillus thuringiensis JS64. The substrate solution containing racemic amine and pyruvate was recirculated through the EMR and inhibitory ketone product was selectively extracted by the membrane contactor until enantiomeric excess of (R)-amine exceeded 95%. Using the reactor set-up with flat membrane reactor (10-mL working volume), kinetic resolutions of alpha-methylbenzylamine (alpha-MBA) and 1-aminotetralin (200 mM, 50 mL) were carried out. During the operation, concentration of ketone product, i.e., acetophenone or alpha-tetralone, in a substrate reservoir was maintained below 0.1 mM, suggesting efficient removal of the inhibitory ketone by the membrane contactor. After 47 and 32.5 h of operation using 5 U/mL of enzyme, 98.0 and 95.5% ee of (R)-alpha-MBA and (R)-1-aminotetralin were obtained at 49.5 and 48.8% of conversion, respectively. A hollow-fiber membrane reactor (39-mL working volume) was used for a preparative-scale kinetic resolution of 1-aminotetralin (200 mM, 1 L). After 133 h of operation, enantiomeric excess reached 95.6% and 14.3 g of (R)-1-aminotetralin was recovered (97.4% of yield). Mathematical modeling of the EMR process including the membrane contactor was performed to evaluate the effect of residence time. The simulation results suggest that residence time should be short to maintain the concentration of the ketone product in EMR sufficiently low so as to decrease conversion per cycle and, in turn, reduce the inhibition of the omega-TA activity.

Abstract
The lipase- and esterase-catalyzed acylations of hydroxylamine and hydrazine derivatives with octanoic acid and ethyl octanoate are described. The influence of solvent and nucleophile on the initial reaction rate was investigated for a number of free and immobilized enzymes. Initial rates were highest in water, but the overall productivity was optimal in dioxane. Octanoic acid (250 g/L) was converted for 93% into the hydroxamic acid in 36 h with only 1% (w/w) Candida antarctica lipase B (Novozym 435) in dioxane at 40 degrees C. This translates to a catalyst productivity of 68.5 g. g(-1). day(-1) and a space time yield of 149 g. L(-1). day(-1), unprecedented figures in the direct reaction of an acid with a nitrogen nucleophile in an organic solvent.

Abstract
Rhodococcus rhodochrous NCIMB 11216 produced nitrile hydratase (320 nkat mg of protein(-1)) and amidase activity (38.4 nkat mg of protein(-1)) when grown on a medium containing propionitrile. These enzymes were able to hydrolyze nitrile groups of both granular polyacrylonitriles (PAN) and acrylic fibers. Nitrile groups of PAN40 (molecular mass, 40 kDa) and PAN190 (molecular mass, 190 kDa) were converted into the corresponding carbonic acids to 1.8 and 1.0%, respectively. In contrast, surfacial nitrile groups of acrylic fibers were only converted to the corresponding amides. X-ray photoelectron spectroscopy analysis showed that 16% of the surfacial nitrile groups were hydrolyzed by the R. rhodochrous enzymes. Due to the enzymatic modification, the acrylic fibers became more hydrophilic and thus, adsorption of dyes was enhanced. This was indicated by a 15% increase in the staining level (K/S value) for C. I. Basic Blue 9.
