Antibody-drug conjugates (ADCs) have become an important therapeutic modality for oncology, with three approved by the FDA and over 60 others in clinical trials. Despite the progress, improvements in ADC therapeutic index are desired. Peptide-based ADC linkers that are cleaved by lysosomal proteases have shown sufficient stability in serum and effective payload-release in targeted cells. If the linker can be preferentially hydrolyzed by tumor-specific proteases, safety margin may improve. However, the use of peptide-based linkers limits our ability to modulate protease specificity. Here we report the structure-guided discovery of novel, nonpeptidic ADC linkers. We show that a cyclobutane-1,1-dicarboxamide-containing linker is hydrolyzed predominantly by cathepsin B while the valine-citrulline dipeptide linker is not. ADCs bearing the nonpeptidic linker are as efficacious and stable in vivo as those with the dipeptide linker. Our results strongly support the application of the peptidomimetic linker and present new opportunities for improving the selectivity of ADCs.

Three illustrative examples are presented from our own approaches to development of drug candidates based on structure-activity relationship analyses. Starting from a lead, 3-(S)-n-butyl-phthalide, an anticonvulsive principle, isolated from Chinese celery seeds, a number of congeners were synthesized and tested. Quantitative structure-activity relationship (QSAR) analyses revealed that the potency depends upon the configuration of substituents around the chiral center at the 3-position, in addition to the hydrophobicity and electronic structure of compounds, and the polarity of substituents in the aromatic moiety. RS-3-n-Butyl-6-amino-phthalide was selected as a candidate for antiepileptic drug. A series of modifications of an antipeptic-ulcer prototype, furazolidone, led to deduction of a lead skeleton. A series of related (hetero) aromatic aldehyde (thio) semicarbazones were synthesized and tested. The QSAR analyses showed that the activity is significantly dependent on the electron density of the (thio) carbonyl group, which is enhanced by the introduction of electrons-donating substituents. Hepatoprotective biphenyl compounds with structures simplified from that of an active principle of a Chinese traditional medicine, were investigated by the analysis of structural parameters obtained from their X-ray crystallography and UV spectrum. The structural requirements for activity were suggested from their configuration and conformation.

Endowing rigid polyurethane foam (PUF) with a good fire-retardancy is essential for improving fire safety. Chemical improvement in fire-retardancy by using reactive-type flame retardants is better because of the disadvantages of traditional additive-type flame retardants. A reactive flame retardant tri-glycidyl phosphate (POG), which was synthesized by using phosphorus oxychloride and glycidol, was bound to the cross-linked network structure of PUF. The effects of POG on the physical-mechanical properties, morphology, thermal stability and fire-retardancy of PUF system were systematically investigated. Research results showed that POG resulted in an improvement in the thermal insulation ability and a slight decrease in the compressive strength of PUF. Furthermore, thermogravimetric analysis certified that the thermal stability and the char yield at 700 C of PUF were significantly enhanced by incorporating POG. The limiting oxygen index increased to 22.3% with rising loading of POG. Moreover, a 30.2% decline in total heat release was achieved, the time to flameout was significantly shortened. Additionally, the vertical burning test illustrated that POG effectively limited the spread of flame and eliminated melt dripping. Further study confirmed that the fire-retardancy of PUF was significantly improved by inhibiting flame in the gas phase and charring in condensed phase.

The design, synthesis, biological evaluation, and X-ray structural studies are reported for a series of highly potent HIV-1 protease inhibitors. The inhibitors incorporated stereochemically defined amide-based bicyclic and tricyclic ether derivatives as the P2 ligands with (R)-hydroxyethylaminesulfonamide transition-state isosteres. A number of inhibitors showed excellent HIV-1 protease inhibitory and antiviral activity; however, ligand combination is critical for potency. Inhibitor 4h with a difluorophenylmethyl as the P1 ligand, crown-THF-derived acetamide as the P2 ligand, and a cyclopropylaminobenzothiazole P2?-ligand displayed very potent antiviral activity and maintained excellent antiviral activity against selected multidrug-resistant HIV-1 variants. A high resolution X-ray structure of inhibitor 4h-bound HIV-1 protease provided molecular insight into the binding properties of the new inhibitor.

Synthetic Route of 497-25-6, A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 497-25-6, Name is Oxazolidin-2-one, molecular formula is C3H5NO2. In a Article，once mentioned of 497-25-6

We describe the synthesis and radical polymerization of series of styrenes with 2-oxazolidone moieties inherited from alpha-amino acids on the side chain. The 2-oxazolidone 2 was readily synthesized through the reaction of diphenyl carbonate with amino alcohols 1 that were prepared through the reduction of the corresponding alpha-amino acids (glycine, l-alanine, l-phenylalanine, l-valine, and l-methionine), in the presence of 1,8-diazabicyclo[5.4.0]-7-undecene as a base catalyst. The subsequent N-substitution reaction of 2-oxazolidone with 4-(chloromethyl) styrene in the presence of sodium hydride produced high yield of the corresponding styrenic compounds 3. Free radical polymerization of these monomers 3 smoothly proceeded in the quantitative monomer-conversion using benzoyl peroxide as a radical initiator to give the corresponding polymers (P3). The thermal properties of the resulting polymers were evaluated by differential scanning calorimetry and thermogravimetric analysis. These oxazolidone-containing polymers effectively adsorbed phenols from aqueous solution, and were also miscible with poly(4-vinylphenol) in the equimolar ratio mixture, because of the effective hydrogen bond interaction involving a carboxyl group of oxazolidone moieties and a hydroxyl group of the phenol.
