The variations in between the theoretically calculated and experimentally determined masses forKM408, a novel phenoxyalkyl derivative as a potential anticonvulsant and analgesic compound… Table 12 Human cytochrome P450 inhibition by compound 4 Compd. 4 Isozyme CYP1A2 CYP2A6 CYP2B6 CYP2C9 CYP2C19 CYP2D6 CYP2E1 CYP3A4 Ki ( ) 23.0 371.0 Inhibition variety Mixed/competitive Mixed/competitive Weak inhibition Slight inhibition Mixed/competitive Mixed/competitive Slight inhibition Weak inhibition157 inhibition of 500 concentration 65 (substrate at two ) 44 (substrate at ten ) 69 (substrate at 25 ) 19 (substrate at 400 ) 80 (substrate at 150.TGF alpha/TGFA Protein Source 0 ) 100 (substrate at 100.0 ) 17 (substrate at 500.0 ) 52 (substrate at 200.0 )54.0 1.For this reason, exact neutral mass loss and solution ion mass filters were used to interrogate information. Six metabolites of KM-408 were identified in extracted samples of rat serum and urine, confirming that KM-408 underwent both phase I and phase II metabolism. As a phase I metabolism, we observed items of oxidation inside the side chain (M1, m/z 272.0975), side chain oxidation and dehydroxylation (M2, m/z 256.1026), dehydroxylation (M3, m/z 242.1233), and side chain hydrolysis at nitrogen (M4, m/z 186.0607). As the important metabolic pathways of phase II biotransformation, we observed the products of O-glucuronidation (M5, m/z 449.1738) with characteristic fragments of m/z 176.0606 and m/z 192.0556 and acetylation (M6, m/z 300.1288) with fragments m/z 159.1181 (Fig. 12).DiscussionWithin the course of our analysis on phenoxyalkylaminoalkanols so far, we’ve got accomplished probably the most promising compounds inside the group of 2,6-dimethyl derivatives.B2M/Beta-2-microglobulin, Human (99a.a, HEK293, His) The replacement of one methyl substituent with chlorine resulted within a series of antiseizure compounds, of which R,S-2N-[(2chloro-6-methylphenoxy)ethyl]amino-1-butanol (4), its R (5) and S (6) enantiomers, also as their hydrochlorides (KM408, 5a and 6, respectively), have been chosen for the extended study as a consequence of the observed pronounced activity in MES in mice soon after ip administration (KM-408 MES ED50 = 13.PMID:23443926 3 mg/ kg, PI = four.83). KM-408, its base 4 and enantiomers five and 6, and their hydrochlorides (5a and 6a, respectively) have been extensively evaluated for their antiseizure activity, in many in vivo tests. The MES test was performed at NINDS as a preliminary screening test for antise.
