Morimoto, Ryohei;Suzuki, Toyoko;Minami, Hideto research published 《 Preparation of Polypropylene-Composite Particles by Dispersion Polymerization》, the research content is summarized as follows. Polypropylene (PP)/poly(benzyl methacrylate) (PBzMA) composite particles were prepared by dispersion polymerization of benzyl methacrylate (BzMA) in the presence of PP particles without a conventional dispersant. The polymerization process yielded a stable emulsion of composite particles with a “currant bun”-like morphol. consisting of a PBzMA core and PP bumps, indicating that the PP particles operate as colloidal stabilizers. Conversely, when BzMA was replaced with styrene as the monomer, dispersion polymerization yielded a large amount of aggregates. Finally, a stable emulsion was formed by copolymerizing a small amount of Me methacrylate (MMA) with styrene. This result suggested that PP must interact with a second polymer to prepare stable composite particles. The surfaces of the PP particles, which are highly hydrophilic due to their carboxyl groups, were involved in the attachment and stabilization of the polymer precipitated in the medium. A film prepared from the obtained PP/PBzMA composite particles was highly hydrophobic and strongly adhesive to a PP sheet.

Type-1 ryanodine receptor (RyR1) is a calcium-release channel localized on sarcoplasmic reticulum (SR) of the skeletal muscle, and mediates muscle contraction by releasing Ca²⁺ from the SR. Genetic mutations of RyR1 are associated with skeletal muscle diseases such as malignant hyperthermia and central core diseases, in which over-activation of RyR1 causes leakage of Ca²⁺ from the SR. We recently developed an efficient high-throughput screening system based on the measurement of Ca²⁺ in endoplasmic reticulum, and used it to identify oxolinic acid (1) as a novel RyR1 channel inhibitor. Here, we designed and synthesized a series of quinolone derivatives based on 1 as a lead compound Derivatives bearing a long alkyl chain at the nitrogen atom of the quinolone ring and having a suitable substituent at the 7-position of quinolone exhibited potent RyR1 channel-inhibitory activity. Among the synthesized compounds, 14h showed more potent activity than dantrolene, a known RyR1 inhibitor, and exhibited high RyR1 selectivity over RyR2 and RyR3. These compounds may be promising leads for clin. applicable RyR1 channel inhibitors.

Here, a series of 1H-pyrazolo-[3,4-b]pyridine-4-carboxylic acid derivatives has been prepared in order to examine the structure-activity relationships (SAR). SAR studies clearly indicated that the steric bulkiness of the substituent on 1H-pyrazolo-[3,4-b]pyridine ring, the position of the distal hydrophobic tail part, and the distance between the distal hydrophobic tail part and the acidic head part are critical for hPPARα agonistic activity. These SAR results are somewhat different from those reported for fibrate-class hPPARα agonists. A representative compound (II) was as effective as fenofibrate in reducing the elevated plasma triglyceride levels in a high-fructose-fed rat model.

Ming, Xiaoqing;Yao, Le;Zhu, He;Zhang, Qi;Zhu, Shiping research published 《 Dramatic and Reversible Water-Induced Stiffening Driven by Phase Separation within Polymer Gels》, the research content is summarized as follows. Responsive polymer materials possessing variable mech. properties have shown promising practical applications, whereas water has clear advantages among the triggers owing to its wide abundance, green characteristics, as well as mild conditions involved. However, ubiquitous water-induced softening would prevent polymer materials from applications with high humidity or aqueous environment. Herein, an unprecedented polymer gel material is reported that exhibits a dramatic and reversible water-induced stiffening base on phase separation, differing from traditional ones that are usually weakened upon hydration due to the plasticizing effect. The material shows a large stiffness change in Young’s modulus (as much as 10⁴ times), which is much larger than that induced by glass transition and comparable to that caused by crystallization-melting process. The polymer materials are fabricated in a facile way by introducing an ionic liquid and a lithium salt into a poly(benzyl methacrylate) network. Moreover, the volume remains almost unchanged during the reversible soft-stiff transition. A universal approach of water-induced stiffening is proposed and verified on various systems. As for demonstration, this material is used for humidity-induced shape memory. This work offers an effective method for developing water-induced stiffened material and will pave the way toward potential applications for water-responsive polymer materials.
