Grafting (S)-2-Phenylpropionic Acid on Coordinatively Unsaturated Metal Centers of MIL-101(Al) Metal-Organic Frameworks for Improved Enantioseparation
Chiral metal-organic frameworks (cMOFs) are emerging chiral stationary phases for enantioseparation owing to their porosity and designability. However, a great number of cMOF materials show poor separation performance for chiral drugs in high-performance liquid chromatography (HPLC). The possible reasons might be the irregular shapes of MOFs and the low grafting degree of chiral ligands. Herein, MIL-101-Ppa@SiO2 was synthesized by a simple coordination post-synthetic modification method using (S)-(+)-2-Phenylpropionic acid and applied as the chiral stationary phase to separate chiral compounds by HPLC. NH2-MIL-101-Ppa@SiO2 prepared via covalent post-synthetic modification was used for comparison. The results showed that the chiral ligand density of MIL-101-Ppa@SiO2 was higher than that of NH2-MIL-101-Ppa@SiO2, and the MIL-101-Ppa@SiO2 column exhibited better chiral separation performance and structural stability. The binding affinities between MIL-101-Ppa@SiO2 and chiral compounds were simulated to prove the mechanism of the molecular interactions during HPLC. These results revealed that cMOFs prepared by coordination post-synthetic modification could increase the grafting degree and enhance the separation performance. This method can provide ideas for the synthesis of cMOFs.
Ibuprofen
Because of its extremely low levels in breastmilk, short half-life and safe use in infants in doses much higher than those excreted in breastmilk, ibuprofen is a preferred choice as an analgesic or antiinflammatory agent in nursing mothers.
Preparation of ( S)-2-Phenylpropionic Acid by CaCl?/CMC Nanoparticles Immobilized Candida rugosa Lipase-Catalyzed Hydrolysis in Micro Aqueous Mixed Organic Solvent Systems
Candida rugosa lipase was immobilized in this study using CaCl?/CMC nanoparticles that yielded a lipase loading capacity of 127 mg/g, with better thermal stability and activity of 91.8%. The hydrolysis of racemic 2-phenylpropionic acid isopropyl ester by free and immobilized Candida rugosa lipase was investigated in the mixed organic-solvent composed of isooctane and methyl tert-butyl ether (9.5:0.5, V/V). The optimal conditions were 35 °C and pH 7.5 for free Candida rugosa lipase hydrolysis. We obtained (S)-2-phenylpropionic acid with 44.85% conversion, 95.75% enantiomeric excess and enantiomeric ratio of 112. The CaCl?/CMC nanoparticles immobilized Candida rugosa lipase possesses high enantioselectivity, with E = 237 at 40 °C and pH 7.5. It was efficiently reusable in four cycles and appropriately enhanced enantioselectivity within 120-240.
Ketoprofen
Although ketoprofen has low levels in breastmilk, one center reported that they had received reports of adverse renal and gastrointestinal side effects in breastfed infants whose mothers were taking ketoprofen. Other agents are preferred, especially while nursing a newborn or preterm infant.
Enantioselective covalent binding of 2-phenylpropionic Acid to protein in vitro in rat hepatocytes
A series of studies was conducted to investigate the potential of (R)- and (S)-2-phenylpropionic acid (2-PPA) to undergo enantioselective covalent binding to protein in freshly isolated rat hepatocytes and to determine whether such covalent binding is dependent on acyl glucuronidation or acyl-CoA formation of 2-PPA. Hepatocytes were incubated with (R,S)-, (R)-, or (S)-[1,2-(14)C(2)]-2-PPA (1 mM), and aliquots of the incubation mixture analyzed for covalent binding, acyl glucuronidation, and acyl-CoA formation over a 3 h period. Covalent binding of 2-PPA to hepatocyte protein was shown to be time-dependent and to be 4.5-fold greater for the (R)-isomer than the (S)-isomer after 3 h of incubation. The enantioselectivity of covalent binding correlated with the enantioselectivity of acyl-CoA formation (R/S = 7.0), but not with acyl glucuronidation (R/S = 0.67) of (R)- and (S)-2-PPA isomers during the 3 h incubation. Inhibition experiments were performed with (R,S)-[1,2-(14)C(2)]-2-PPA (1 mM) incubated with hepatocytes in the presence or absence of trimethylacetic acid (2 mM) or (-)-borneol (1 mM) for the inhibition of 2-PPA-CoA formation and 2-PPA acyl glucuronidation, respectively. Covalent binding of 2-PPA to hepatocyte protein exhibited a 53% decrease in cells treated with trimethylacetic acid, where a 66% decrease in 2-PPA-CoA formation occurred. Conversely, treatment with (-)-borneol, which completely inhibited 2-PPA acyl glucuronidation, only decreased covalent binding by 18.7%. These results indicate that metabolism of 2-PPA by acyl-CoA formation leads to the generation of reactive acylating CoA-thioester species that can contribute to protein covalent binding in a manner that is more extensive than the respective acyl glucuronides.
