In 2022,Gu, Binbin; Hou, Anwei; Dickschat, Jeroen S. published an article in Beilstein Journal of Organic Chemistry. The title of the article was 《The stereochemical course of 2-methylisoborneol biosynthesis》.Name: Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate The author mentioned the following in the article:

Both enantiomers of 2-methyllinalyl diphosphate (2-Me-LPP) were synthesized enantioselectively using Sharpless epoxidation as a key step and purification of enantiomerically enriched intermediates through HPLC separation on a chiral stationary phase. Their enzymic conversion with 2-methylisoborneol synthase (2MIBS) demonstrated that (R)-2-Me-LPP is the on-pathway intermediate, while a minor formation of 2-methylisoborneol from (S)-2-Me-LPP might be explained by isomerization to 2-Me-GPP and then to (R)-2-Me-LPP. In the experiment, the researchers used Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate(cas: 6381-59-5Name: Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate)

Category: alcohols-buliding-blocksIn 2013 ,《Characterization of salt interferences in second-harmonic generation detection of protein crystals》 appeared in Journal of Applied Crystallography. The author of the article were Closser, R. G.; Gualtieri, E. J.; Newman, J. A.; Simpson, G. J.. The article conveys some information:

Studies were undertaken to assess the merits and limitations of second-harmonic generation (SHG) for the selective detection of protein and polypeptide crystal formation, focusing on the potential for false positives from SHG-active salts present in crystallization media. The SHG activities of salts commonly used in protein crystallization were measured and quant. compared with reference samples. Out of 19 salts investigated, six produced significant background SHG and 15 of the 96 wells of a sparse-matrix screen produced SHG upon solvent evaporation SHG-active salts include phosphates, hydrated sulfates, formates and tartrates, while chlorides, acetates and anhydrous sulfates resulted in no detectable SHG activity. The identified SHG-active salts produced a range of signal intensities spanning nearly three orders of magnitude. However, even the weakest SHG-active salt produced signals that were several orders of magnitude greater than those produced by typical protein crystals. In general, SHG-active salts were identifiable through characteristically strong SHG and negligible two-photon-excited UV fluorescence (TPE-UVF). Exceptions included trials containing either potassium dihydrogen phosphate or ammonium formate, which produced particularly strong SHG, but with residual weak TPE-UVF signals that could potentially complicate discrimination in crystallization experiments using these precipitants. In the experiment, the researchers used many compounds, for example, Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate(cas: 6381-59-5Category: alcohols-buliding-blocks)

The author of the article were Iwaki, Takehiko; Tanaka, Taisaku; Miyazaki, Kazuo; Suzuki, Yamato; Okamura, Yoshihiko; Yamaki, Akira; Iwanami, Makoto; Morozumi, Naomi; Furuya, Mayumi; Oyama, Yoshiaki. The article conveys some information:

Natriuretic peptide receptor A (NPR-A) agonists were evaluated in vivo by optimizing the structure of quinazoline derivatives to improve agonistic activity for rat NPR-A. A 1,4-Cis-aminocyclohexylurea moiety at 4-position and hydroxy group of D-alaninol at 2-position on the quinazoline ring were found to be important factors in improving rat NPR-A activity. The authors identified potent quinazoline and pyrido[2,3-d]pyrimidine derivatives against rat NPR-A, with double-digit nanomolar EC50 values. The in vivo results showed that compound 56b (1-((1S,4S)-4-((6-(3-fluorophenyl)-2-(((R)-1-hydroxypropan-2-yl)amino)pyrido[2,3-d]pyrimidin-4-yl)amino)cyclohexyl)-3-((R)-1-hydroxy-3-methylbutan-2-yl)urea) administered at 1.0 mg/kg/min significantly increased plasma cGMP concentration and urine volume in rats.

Dearomative cycloaddition reactions represent an ideal means of converting flat arenes into three-dimensional architectures of increasing interest in medicinal chem. Quinolines, isoquinolines, and quinazolines, despite containing latent diene and alkene subunits, are scarcely applied in cycloaddition reactions because of the inherent low reactivity of aromatic systems and selectivity challenges.
