Estimation of Circulating Drug Metabolite Exposure in Human Using In Vitro Data and Physiologically Based Pharmacokinetic Modeling: Example of a High Metabolite/Parent Drug Ratio

(R)-4-((4-(((4-((tetrahydrofuran-3-yl)-oxy) benzo[d] isoxazol-3-yl) oxy)methyl) piperidin-1-yl) methyl) tetrahydro-2H-pyran-4-ol (TBPT), a serotonin-4 receptor partial agonist, is metabolized to two metabolites: an N-dealkylation product [(R)-3-(piperidin-4-ylmethoxy)-4(( tetrahydrofuran-3-yl) oxy) benzo[d] isoxazole (M1)] and a cyclized oxazolidine structure [7-(((4-(((R)-tetrahydrofuran-3-yl) oxy) benzo [d] isoxazol-3-yl) oxy) methyl) octahydro-3H (M2)]. After administration of TBPT to humans the exposure to M1 was low and the exposure to M2 was high, relative to the parent drug, despite this being the opposite in vitro. In this study, projection of the plasma metabolite/parent (M/P) ratios for M1 andM2 was attempted using in vitro metabolism, binding, and permeability data in static and dynamic physiologically based pharmacokinetic (PBPK) models. In the static model, the fraction of parent clearance yielding the metabolite (which also required taking into account secondary metabolites of M1 and M2), the clearance of the metabolites and parent, and an estimate of the availability of the metabolites from the liver were combined to yield estimated parent/metabolite ratios of 0.32 and 23 for M1 and M2, respectively. PBPK modeling that used in vitro and physicochemical data input yielded estimates of 0.26 and 20, respectively. The actual values were 0.12 for M1/TBPT and 58 for M2/TBPT. Thus, the ratio for M1 was overpredicted, albeit at values less than unity. The ratio for M2/TBPT was underpredicted, and the high ratio of 58 may exceed a limiting ceiling of the approach. Nevertheless, when considered in the context of determining whether a potential circulating metabolite may be quantitatively important prior to administration of a drug for the first time to humans, the approaches succeeded in highlighting the importance of M2 (M/P ratio >> 1) relative to M1, despite M1 being much greater than M2 in vitro.

Induction of Herbicide Detoxifying Enzyme in Maize by Chiral 3-Dichloroacetyl Oxazolidine

Safeners are important tools used to ensure to safe useof herbicide. The aim of this paper is to evaluate the protective effect of four safeners (R-28725, 3-dichloroacetyl oxazolidine and its two optical isomers) and investigate the mechanism of herbicide detoxication by safener. Laboratory studies were conducted to evaluate the effectiveness of safeners for protecting maize from the residues of preemergent herbicide fomesafen in Northeast Agricultural University, China. Physiological and biochemical tests were herein conducted under laboratory conditions, by using seed treatment with safeners and soil treatment with fomesafen, respectively. R-28725 provoked high glutathione level, glutathione-Stransferase activity and affinity of glutathione-S-transferase than other safeners, but R-isomer treatment resulted in complete reversal of injury caused by fomesafen.

Binding motif of ebselen in solution: chalcogen and hydrogen bonds team up

Ebselen (2-phenyl-1,2-benzoselenazol-3(2H)one), a glutathione peroxidase mimic, is active against several RNA viruses, among others the retrovirus responsible for the COVID-19 pandemic. In this paper Se-77 and H-1 NMR studies of ebselen are reported and they identify the chalcogen bond (ChB) and hydrogen bond (HB) that are central in the landscape of interactions formed by the compound in solution. The selenium atom and the hydrogen atom at the C7 carbon act as ChB and HB donors and the O and N atoms of neutral molecules function as acceptors. The ChB and HB give rise to a bifurcated supramolecular synthon, which fastens the interaction acceptor opposite to the N-Se covalent bond of the selenazole ring. It is known that the biologically important reaction of ebselen with cysteine thiol groups is favoured when selenium acts as a chalcogen bond donor.

Crystal structure and magneto-structural investigation of alkoxido bridged dinuclear Fe(III) complexes with 1,3-oxazolidine ligands

Four 1,3-oxazolidine based ligands (H2L1-H2L4) were synthesized in solvent-free condition from the reaction of amino alcohols (2-amino-2-(hydroxymethyl)-1,3-propanediol or 2-amino-2-ethy1-1,3-propanediol) and 2-acetylpyridine or 2-pyridinecarboxaldehyde at 110 T. Four new dinuclear Fe(III) complexes, [Fe-2(HL1)(N-3)(4)] (1), EFe2(HL2)(N-3)(4)] (2), [Fe-2(HL3)(N-3)(4)] (3) and [Fe-2(HL4)(N-3)(4)] (4), were synthesized with a similar procedure by the reaction of H2L1-4, Fe(NO3)(3).9H(2)O and NaN3 in 1:1:2 molar ratios in methanol. The ligands and complexes were characterized by elemental analysis and spectroscopic methods. The structure of complexes was solved by single-crystal X-ray diffraction analysis which showed complexes 1-4 to be alkoxido-bridged dinuclear Fe(III) complexes. The structural studies indicated that the crystal structure of 2, 3 and 4 consist of a centrosymmetric dinuclear Fe(III) complexes while the asymmetric unit in 1 consists of two halves of the two independent molecules. The Fe(III) ions have similar coordination environments (cis-FeN4O2) in all of 1-4 which can be described as distorted octahedral geometry. The 1,3-oxazolidine ligands act as mononegative tridentate N2O-donor ligand in 1-4. Two azide groups are also coordinated to each Fe(III) ion as terminal monodentate ligands. The alcoholic arms of the 1,3-oxazilidine ligands act as bridging groups between Fe(III) ions and the Fe center dot center dot center dot Fe distances through these bridges are in the range of 3.157-3.198 A. Magnetic studies in 2-300 K range reveal antiferromagnetic interactions between the Fe(III) ions with values for the magnetic coupling constants in the range -9.4 cm(-1) to -9.7 cm(-1), with H =-2(f)(S1S2) (C) 2019 Elsevier Ltd.

Crystal structure of 5-chloro-1,3-bis[2-(2oxo-1,3-oxazolidin-3-yl)ethyl]-1H-benz-imidazol-2(3H)-one

In the title compound, C17H19ClN4O5, the benzimidazole fused -ring system is essentially planar, the maximum deviation from the mean plane being 0.06 (1) angstrom. Both oxazolidine rings are nearly planar, the maximum deviations from the mean planes are 0.071 (13) and 0.070 (10) angstrom. The dihedral angle between the mean planes of the oxazolidine rings is 69.9 (7). The benzimidazole mean plane makes the dihedral angles of 43.9 (6) and 45.6 (6)degrees with the two oxazolidine rings. In the crystal, the molecules are linked together by weak C-H center dot center dot center dot O hydrogen bonds building zigzag tapes running along the c axis. The Cl atom is split over two positions with an occupancy ratio of 0.567 (7):0.433 (7). This means that the reaction yields two isomers, A and B; the A component has the Cl-atom substituent in the 5-position of the benzimidazolone ring and the B component has the Cl atom in the 6 -position. The two isomers form the disordered co-crystal, with a nearly half Cl atom in each of them, as indicated by the occupancy ratio. The crystal structure was refined as an inversion twin.

Nutrient composition, glucosinolate and vinyl-oxazolidine-thione profiling of Indian rapeseed (Brassica juncea Coss.) meal

Presence of antinutritional factor(s) in any feedstuff impedes effective nutrient utilization by animals, besides causing specific adverse effects. This study includes eighteen different batches of Indian rapeseed (Brassica juncea Coss.) meal (RSM) sampled over a period of nine months for their evaluation in terms of nutrient composition, glucosinolate (GL) and vinyl-oxazolidine-thione (VOT) concentrations. Results showed that RSM contained a mean value (on dry basis) of crude protein (36.7%), ether extract (1.1%), ash (7.6%), crude fibre (10%), neutral detergent fibre (25%), acid detergent fibre (16.5%), hemicellulose (8.6%), total carbohydrates (54.7%), non-fibrous carbohydrates (29.7%), total digestible nutrients (77.9%) and metabolizable energy (11.7 MJ/kg). Furthermore, antinutritional factors like GL (mu mol/g) and VOT (mg/g) are presented to be in the range of 36.2-72.2 (mean: 52) and 0-3.2 (mean: 1.0) respectively. Based on the species-wise tolerance limit for GL, the optimum inclusion level of RSM recommended for ruminants, pigs, rabbits, rats, poultry and fish is 15.6%, 1.5%, 13.5%, 1%, 10.4% and 6.9% respectively. Results of the present study are expected to maximize precision ration balancing for enhanced nutrient utilization whilst also curtailing any possible adverse effects of GL and VOT on production performance of animals.
