We evaluated the effectiveness of seven commercial hydrolytic enzymes to simultaneously hydrolyze N-glucuronides (using the antibacterial triclocarban as example compound) and other conjugates (using select phenols and parabens as examples) by using on-line solid phase extraction high performance liquid chromatography-isotope dilution-tandem mass spectrometry.
For example, compounds S-1693 and S-3066 were classified as inhibitors by qHTS, each producing ∼30% inhibition at maximal concentrations (77 µM), but ITC failed to provide convincing evidence of binding.
For example, compounds 1 and 3 have identical overall charges of +4, yet their association rate constants differ by 1 order of magnitude.
For example, compounds 5 and 7 were found by dynamic light scattering to form large aggregates (>80 nm radii) at 1 μM.
For example, compounds 13 and 16 both have an abundant peak at m/z 97, due to the availability of a hydrogen on the sp carbon in close proximity to the sulfate group.
Analysis of the structure binding relationships of the series of ESG analogues (4 12) reveals that GSH adducts formed with either rigid (4 9) or flexible electrophiles result in compounds that bind with similar affinity to Kef (for example, compounds 6 and 12).
In contrast, although the series of β-carbon-substituted carboxylic acids, including, for example, compounds 26 and 29, also gained function at the C4.57G mutant (Fig. 7 E, F), these compounds were substantially less potent at hFFA2-C4.57G hFFA2-C4.57G2, suggesthan that additional residues bFFA2esuggesting likely thatontribute to this additionalthe bFFA2 ligand SAresidues
For example, compounds 5 and 6, which bind to cIAP1/2 with high affinities (Ki = 3.2 11.6 nM) and have weak affinities (Ki = 2 3 μM) for XIAP, have IC50 values of 46 and 17 nM, respectively, in inhibition of cell growth in the MDA-MB-231 cell line.
Hydroxylation, epoxidation, and formation of O-containing heterocycles (for example compounds 31, 32, and 33, Figure 7) increase the complexity of race B liquid and polymer hydrocarbons.
Example compounds for A and B might be water and sodium chloride (table salt), respectively.
