A high-throughput screening (HTS) campaign identified a fundamentally new mGlu₇ NAM chemotype, based on an Et 8-methoxy-4-(4-phenylpiperazin-1-yl)quinolinecarboxylate core. The initial hit, VU0226390 (I), was a potent mGlu₇ NAM (IC₅₀ = 647 nM, 6% L-AP4 min) with selectivity vs. the other group III mGlu receptors (>30μM vs. mGlu₄ and mGlu₈). A multi-dimensional optimization effort surveyed all regions of this new chemotype, and found very steep SAR, reminiscent of allosteric modulators, and unexpected piperazine mimetics (whereas classical bioisosteres failed). While mGlu₇ NAM potency could be improved (IC₅₀s ∼ 350 nM), the necessity of the Et ester moiety and poor physiochem. and DMPK properties precluded optimization towards in vivo tool compounds or clin. candidates. Still, this hit-to-lead campaign afforded key medicinal chem. insights and new opportunities.

Attempts to directly drug the important oncogene KRAS have met with limited success despite numerous efforts across industry and academia. The KRAS^G12C mutant represents an “Achilles heel” and has recently yielded to covalent targeting with small mols. that bind the mutant cysteine and create an allosteric pocket on GDP-bound RAS, locking it in an inactive state. A weak inhibitor at this site was optimized through conformational locking of a piperazine-quinazoline motif and linker modification. Subsequent introduction of a key Me group to the piperazine resulted in enhancements in potency, permeability, clearance, and reactivity, leading to identification of a potent KRAS^G12C inhibitor with high selectivity and excellent cross-species pharmacokinetic parameters and in vivo efficacy.

Khan, Nawaz Mohammed;Kumar, Pawan;Hemanth, Sudheer Kumar K.;Bharath, Rathna Kumar P. research published 《 Synthesis, molecular bioinformatics modelling, and antimicrobial evaluation of some novel oxadiazole fluoroquinolone derivatives》, the research content is summarized as follows. A series of oxadiazole fluoroquinolone derivatives I [Ar = Ph, 4-aminophenyl, 2-hydroxy-4-aminophenyl; R¹ = Et, c-Pr; R² = imidazol-1-yl, piperazin-1-yl] were synthesized with added derivatives such as Ph, aminophenyl, amino hydroxyphenyl along with cyclopropyl, Et, piperazine and imidazole. All of the newly produced mols. I were characterized by IR, ¹H-NMR, mass spectrometry and elemental anal. technique and screened for docking stimulation to find out binding modes of synthesized derivatives with 3FV5, 5IMW and 5ESE and evaluated for in-vitro antimicrobial activity. From this study, it was found that the compound I [Ar = 4-aminophenyl, R¹ = c-Pr, R² = imidazol-1-yl] showed good antibacterial activity against Gram-pos. (Staphylococcus aureus), compound I [Ar = 2-hydroxy-4-aminophenyl, R¹ = c-Pr, R² = imidazol-1-yl] showed good antibacterial activity against Gram-neg. (Escherichia coli), and compound I [Ar = 2-hydroxy-4-aminophenyl, R¹ = c-Pr, R² = piperazin-1-yl] showed good antifungal activity against fungi (Saccharomyces cerevisiae) in comparison with standard drugs (Ciprofloxacin and fluconazole). The zone of inhibition and min. inhibitory concentration studies was performed on synthesized compounds I. The analogs of oxadiazole flouroquinolone I are suggested to be potent inhibitors with sufficient scope for further exploration.

Kim, Siyeon;Ahn, Jung Oh;Kim, Kyung-Min;Lee, Chang-Ha research published 《 Effects of the mobile phase on the chromatographic separation of L-lysine and 5-aminovaleric acid》, the research content is summarized as follows. 5-Aminovaleric acid (5AVA), an attractive bio-based carbon-5 building block for polymer synthesis, is produced from L-lysine. However, their structural similarity makes separating 5AVA from L-lysine challenging. The simulated moving bed (SMB), continuous chromatog. separation process provides a solution with high productivity and low eluent consumption. Here, the effects of the mobile phase on the separation of 5AVA and L-lysine on a C18 column are reported. Pre-column derivatization using diethylethoxymethylene malonate enhanced the detection sensitivity and separation performance, which was strongly affected by the phosphate buffer pH. A 70/30 (volume/volume) mobile phase of 20 mM phosphate buffer at pH 6.8 and acetonitrile showed the best separation performance in isocratic mode. The selectivity at adsorption equilibrium was determined from pulse experiments, and the optimal operating conditions of the SMB process were determined from the equilibrium constants of both components. The feasibility of separating 5AVA and L-lysine by the SMB process was confirmed with purity and recovery of greater than 99%. The SMB process using pre-column derivatization can provide the competitiveness of the bio-based chem. production because separation processes typically contribute to more than 70% of the total production cost.

A well-defined glycopolymer based fluorescence active nanogel has been prepared via the combination of reversible addition-fragmentation chain transfer (RAFT) polymerization and Diels-Alder (DA) “”click”” chem. To prepare the nanogel, initially, a functional AB block copolymer (BCP) poly(pentafluorophenyl acrylate)-b-poly(furfuryl methacrylate) (PPFPA-b-PFMA), having activated pentafluorophenyl ester group, was synthesized via RAFT polymerization The activated pentafluorophenyl functionality was replaced by the amine functionality of glucosamine to introduce the amphiphilic BCP poly[2-(acrylamido) glucopyranose]-b-poly(furfuryl methacrylate) (PAG-b-PFMA). Furthermore, the terminal acid (-COOH) functionality of the RAFT agent was modified by gelatin QDs (GQDs) to generate fluorescence active glycopolymer. An anticancer drug, Doxorubicin, was loaded in the micelle via the successive addition of the drug mol. and crosslinking using dithio-bismaleimidoethane (DTME), a REDOX responsive cross-linker. The anticancer activity of the drug loaded nanogel was observed over MBA-MD-231, human breast cancer cell line, and monitored via fluorescence spectroscopy and flow cytometric analyses (FACS). The cytotoxicity of the prepared glycopolymer based nanogel over the MBA-MD-231 cell line was assessed via MTT assay test, and it was observed that the synthesized nanogel was noncytotoxic in nature.

Defect passivation via additive and energetic modification via interface engineering are two effective strategies for achieving high-performance perovskite solar cells (PSCs). Here, the synergies of pentafluorophenyl acrylate when used as additive, in which it not only passivates surface defect states but also simultaneously modifies the energetics at the perovskite/Spiro-OMeTAD interface to promote charge transport, are shown. The additive-induced synergy effect significantly suppresses both defect-assisted recombination and interface carrier recombination, resulting in a device efficiency of 22.42% and an open-circuit voltage of 1.193 V with excellent device stability. The two photovoltaic parameters are among the highest values for polycrystalline CsFormamidinium/Methylammonium (FAMA)/FAMA based n-i-p structural PSCs using low-cost silver electrodes reported to date. The findings provide a promising approach by choosing the dual functional additive to enhance efficiency and stability of PSCs.

Uncontrolled systemic inflammatory immune triggering has hampered the clin. translation of several classes of small-mol. immunomodulators, such as imidazoquinoline TLR7/8 agonists for vaccine design and cancer immunotherapy. By taking advantage of the inherent serum-protein-binding property of lipid motifs and their tendency to accumulate in lymphoid tissue, we designed amphiphilic lipid-polymer conjugates that suppress systemic inflammation but provoke potent lymph-node immune activation. This work provides a rational basis for the design of lipid-polymer amphiphiles for optimized lymphoid targeting.

Ganda, Sylvia; Wong, Chin Ken; Stenzel, Martina H. published the artcile< Corona-Loading Strategies for Crystalline Particles Made by Living Crystallization-Driven Self-Assembly>, HPLC of Formula: 71195-85-2, the main research area is corona crystalline particle crystallization selfassembly.

Self-assembled block copolymer (BCP) nanoparticles offer exciting opportunities for drug delivery applications. A key feature of using BCP nanoparticles for drug delivery is their ability to accommodate therapeutic cargoes within their particle core. This has become widely established for BCP nanoparticles with an amorphous core. The same, however, cannot be achieved with BCP nanoparticles with a crystalline core. This is because the encapsulation of therapeutic cargoes in a crystalline particle core disrupts crystallinity and ultimately leads to particle disassembly. Herein, we present several strategies to incorporate therapeutics and other functional cargoes onto the surface of crystalline particles, as this helps to ensure that the crystallinity of the particle core is maintained and the particle morphol. is hence unaffected. As a platform to showcase our strategies, in this study, we used biodegradable and bioactive 2D glycoplatelets prepared by living crystallization-driven self-assembly (CDSA). Specifically, we show that we can incorporate either an anticancer drug, doxorubicin (DOX), or a fluorescent dye, Cyanine5 (Cy5), onto the surface of glycoplatelets by seeded growth of prefunctionalized polymers or via postmodification using polymers with reactive handles. We believe that the strategies presented herein are versatile and should thus be applicable to other CDSA systems. Overall, our findings present new opportunities for crystalline particles to be used in drug delivery application.

Here, the authors report the synthesis of glycopolymer brushes on the silicon substrate by interface-mediated reversible addition-fragmentation chain transfer (RAFT) polymerization of pentafluorophenyl acrylate as well as subsequent attachment of D-glucosamine to determine specific and nonspecific protein interactions. The root-mean-square roughness of the glycopolymer brushes is only �.1 nm, indicating unstable distribution of the collapsed glycopolymer chains on the surface. The water contact angle of glycopolymer brush was determined as �3� indicating a hydrophilic behavior. The results of fluorescence microscopy studies indicated that the glycopolymer brushes have specific interaction with fluorescence-labeled Con A and nonspecific interaction with fluorescence-labeled bovine serum albumin. The glycopolymer brushes tested here are hoped to enlarge to the knowledge of recognition phenomena at the surface of polymer brushes. �2017 Wiley Periodicals, Inc. J. Appl. Polym.
