The enantioselectivity of the lipase from Pseudomonas cepacia (PCL) in the transesterification of 2-phenyl-1-propanol 1 was studied using a series of vinyl 3-arylpropanoates as acyl donors. The most enantioselective transesterification reaction of the alcohol was attained by using vinyl 3-(p-iodophenyl)- or 3-(p-trifluoromethylphenyl)propanoates, with enantiomer ratios, E, of 116 and 138, respectively. Vinyl 3-phenylpropanoate was also effective for the resolution of 1 mediated by lipases from P. fluorescens and porcine pancreas and for the PCL-catalysed transesterification of several 2-phenyl-1-alkanols. The enantiomeric resolution of 1 was practically carried out by the first enantioselective transesterification using PCL and vinyl 3-(p-iodophenyl)propanoate to afford (R)-1 and then the enantioselective hydrolysis of the resultant ester to afford (S)-1.

As an important bridge between the micro and macro material world, chemistry is one of the main methods and means for humans to understand and transform the material world. Formula: C10H10O4, In a article, mentioned the application of 3663-79-4, Name is Methyl 1,4-Benzodioxane-2-carboxylate, molecular formula is C10H10O4

2-Substituted 1,4-benzodioxanes, such as 2-cyano-, 2-methoxycarbonyl-, 2-aminocarbonyl-, and 2-formyl-1,4-benzodioxane, are key synthons that for the most part are never described as enantiomers or are inadequately characterized for enantiomeric purity. They were prepared by quantitative N,N-dichlorination of (R)- and (S)-2-aminomethyl-1,4-benzodioxane and successive functional group conversions in high yields without any racemization of the stereogenic benzodioxane C(2).

In an article, 4442-53-9, molcular formula is C9H8O4, Name is 2,3-Dihydrobenzo[b][1,4]dioxine-5-carboxylic acid, molcular weight is 180.16, introducing its new discovery.

BRCTs are phosphoserine-binding domains found in proteins involved in DNA repair, DNA damage response and cell cycle regulation. BRCA1 is a BRCT domain-containing, tumor-suppressing protein expressed in the cells of breast and other human tissues. Mutations in BRCA1 have been found in ca. 50% of hereditary breast cancers. Cell-permeable, small-molecule BRCA1 inhibitors are promising anticancer agents, but are not available currently. Herein, with the assist of microarray-based platforms, we have discovered the first cell-permeable protein-protein interaction (PPI) inhibitors against BRCA1. By targeting the (BRCT)2 domain, we showed compound 15a and its prodrug 15b inhibited BRCA1 activities in tumor cells, sensitized these cells to ionizing radiation-induced apoptosis, and showed synergistic inhibitory effect when used in combination with Olaparib (a small-molecule inhibitor of poly-ADP-ribose polymerase) and Etoposide (a small-molecule inhibitor of topoisomerase II). Unlike previously reported peptide-based PPI inhibitors of BRCA1, our compounds are small-molecule-like and could be directly administered to tumor cells, thus making them useful for future studies of BRCA1/PARP-related pathways in DNA damage and repair response, and in cancer therapy.

We recently identified a peptide-peptoid hybrid, PPS1, which specifically recognized lipid-phosphatidylserine (PS). PPS1 consists of distinct positively charged and hydrophobic residue-containing regions. The PPS1 monomer was inactive, but the dimeric form, PPS1D1, displayed strong cytotoxicity to lung cancer cells compared to normal cells in vitro, and reduced the tumor growth in vivo. The minimum pharmacophore of PPS1D1 showed that the first (methionine) and fourth (N-lysine) residues were not important for PPS1D1 cytotoxic activity. In this study, we further investigated these two residues, in particular the fourth residue that lies between the most important four-residue hydrophobic region and two positively charged residues, to determine whether replacements of these moieties could gain activity improvements or render PPS1D1 totally insensitive for binding recognition. The positively charged fourth residue N-lysine was replaced with substituents having varied physiochemical properties, such as aromatic-hydrophobic, aliphatic-alicyclic, heterocyclic, and negatively charged residues, developing a mini-library of 39 derivatives. The standard 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium (MTS) colorimetric and/or the calcein AM cell viability assays performed on HCC4017 lung cancer cells indicated that the fourth position of PPS1D1 was insensitive to most changes, except that reversal of the negative charge significantly affected the activity. This observation may be due to the neutralization of the nearby positively charged residue that is essential for binding. In addition, shortening each monomeric sequence by eliminating the methionine at the first position did not affect the activity.
