Methods and compositions for improving performance of flocculants in an industrial production process. Methods include pH triggered cross-linking reaction between a flocculating agent, such as dextran, and a composition comprising a boronic acid-containing polymer. The pH trigger can be provided by a fluid having a pH of 8 or more. The production process can be a Bayer Process and the fluid is caustic liquor or slurry in the fluid circuit of the Bayer, wherein the reaction time is reduced over conventional methods and the cross-linked dextran composition effectuates improved flocculation of the trihydrate particles.

Future efforts will undeniably focus on the diversification of the new catalytic transformations. These may comprise an expansion of the substrate scope from aromatic and heteroaromatic compounds to other hydrocarbons.

Seven delocalized aromatic molecules with electron-donating and electron-withdrawing groups are applied as voltage stabilizers to improve the insulation properties of polyethylene blends. Voltage stabilizers 1 wt% are added into the blends (90 wt% low-density polyethylene and 10 wt% high density polyethylene) by diffusion loading method. Electrical measurements including electrical treeing, space charge distribution, and direct current conductivity are conducted to disclose their effects. The results show that the co-existence of matched electron-donating and electron-withdrawing groups in the molecules is favorable for the insulation properties. A 50% increase of tree initiation voltage is achieved with the addition of 3-aminobenzoic acid, which is also able to inhibit the space charge and decrease the conductivity at lower temperature. Besides, the grafting sample of the optimal molecule is successfully prepared and displayed enhanced electrical properties. Finally, the common internal mechanism of the delocalized molecules on different electrical properties is revealed.

An aminomethylthiazole pyrazole carboxamide lead 3 with good in vitro antiplasmodial activity [IC50: 0.08 muM (K1, chloroquine and multidrug resistant strain) and 0.07 muM (NF54, chloroquine sensitive strain)] and microsomal metabolic stability was identified from whole cell screening of a SoftFocus kinase library. Compound 3 also exhibited in vivo activity in the P. berghei mouse model at 4 × 50 mg/kg administration via the oral route, showing 99.5% activity and 9 days survival and showed low in vitro cytotoxicity. Pharmacokinetic studies in rats revealed good oral bioavailability (51% at 22 mg/kg) with a moderate rate of absorption, reasonable half-life (t1/2 3 h), and high volume of distribution with moderately high plasma and blood clearance after IV administration. Toward toxicity profiling, 3 exhibited moderate potential to inhibit CYP1A2 (IC50 = 1.5 muM) and 2D6 (IC50 = 0.4 muM) as well as having a potential hERG liability (IC50 = 3.7 muM).

Healthcare careers for chemists are once again largely based in laboratories, although increasingly there is opportunity to work at the point of care, helping with patient investigation. Reference of 64068-00-4

Spinal muscular atrophy (SMA) is an autosomal recessive degenerative neuromuscular disorder caused by a mutation in the SMN1 gene, characterized by loss of spinal motor neurons leading to progressive muscle weakness. Advances in the molecular biology of SMA have resulted in the development of therapeutic agents that target survival motor neuron (SMN) protein production. These SMN-modifying treatments include mRNA therapies and gene transfer therapy. Treatments that modulate SMN2 mRNA alternative splicing include antisense oligonucleotide (ASO) and small-molecule agents. The best studied is nusinersen (Spinraza), an ASO approved for use to treat patients with SMA of all types. Small molecules (risdiplam and branaplam) act systemically and centrally to increase SMN protein levels via alternative splicing. Another SMN-modifying treatment is gene transfer therapy with AAV9 (adeno-associated virus 9) with AVXS-101, which has recently been approved in the U.S. under the name onasemnogene abeparvovec (Zolgensma). Risdiplam and AVXS-101 are currently in advanced phase III trials. Data on risdiplam is soon to be submitted to regulatory agencies for approval. This article discusses risdiplam?s preliminary clinical trial results and contrasts risdiplam with other SMN-modifying therapies with respect to mechanism of action, tissue distribution and drug delivery. Preliminary data from patients treated with risdiplam show a strong clinical response in motor, respiratory and swallowing function in type 1 infants. These robust effects were observed despite the fact that risdiplam-treated infants (when comparing median mean age at time of first dose) were older than the infants enrolled in either the nusinersen or in the AVXS-101 studies. Effects were also seen even among later-onset SMA in patients who were significantly older and had more advanced disease with chronic changes (e.g., severe scoliosis) than did other later-onset SMA patients studied. The level of response at this stage of disease would indicate perhaps a therapeutic advantage to systemic treatment compared to a CNS-restricted site of action. Risdiplam, thus far, has been shown to be safe and well tolerated with no drug-related adverse events resulting in drug discontinuation reported. As risdiplam and other SMN-modifying therapies are proven effective and approved for use, understanding the differences in mechanism of action, drug distribution and method of delivery gains relevance with regards to future therapeutic decisions. Results of the ongoing presymptomatic studies currently underway using each of the SMN-modifying therapies (risdiplam, nusinersen and AVXS-101) in a homogenous population (presymptomatic) are likely to shed light as to whether any one specific treatment offers a therapeutic advantage.

When 3-chloro-4,5-diaminopyridazine (2) was treated with sodium methylmercaptide in refluxing N,N-dimethylformamide, two heterocycles were formed and isolated, neither of which was the expected 3-methylthio-4,5-diaminopyridazine (3).A thorough spectral analysis of these heterocycles showed them to be 4-methylthioimidazo<4,5-d>pyridazine (5) and imidazo<4,5-d>pyridazine-4-thione (6).N,N-Dimethylformamide was found to provide the one carbon unit required for the formation of 5.The origin of 6 was shown to be a result of S-demethylation of 5.S-Demethylation of 3 could also be effected with sodium methylmercaptide in methyl sulfoxide without the occurrence of annulation.In methyl sulfoxide the process of demethylation was accelerated and occurred at lower temperature.
