Caffeic acid phenethyl ester (CAPE) is an ester of a hydroxycinnamic acid (phenylpropanoid) and a phenylethanoid (2-phenylethanol; 2-PE), which has long been used in traditional medicine. Here, we synthesized 54 hydroxycinnamic acid-phenylethanoid esters by feeding 64 combinations of hydroxycinnamic acids and phenylethanols to Escherichia coli harboring the rice genes OsPMT and Os4CL. The same approach was applied for ester synthesis with caffeic acid and eight different phenyl alcohols. Two hydroxycinnamoyl phenethyl esters, p-coumaroyl tyrosol and CAPE, were also synthesized from glucose using engineered E. coli by introducing genes for the synthesis of substrates. Consequently, we synthesized approximately 393.4 mg/L p-coumaroyl tyrosol and 23.8 mg/L CAPE with this approach. Overall, these findings demonstrate that the rice PMT and 4CL proteins can be used for the synthesis of diverse hydroxycinnamoyl phenylethanoid esters owing to their promiscuity and that further exploration of the biological activities of these compounds is warranted.

A total synthesis of an anticancer xanthone natural product termicalcicolanone A utilizing multiple nucleophilic aromatic substitutions and pericyclic reactions has been developed. The pyrano[3,2-b]xanthen-6-one scaffold was constructed via NHC-catalyzed aroylation to produce the benzophenone intermediate, Claisen cyclization to form the pyran ring, and intramolecular 1,4-addition to construct the xanthone framework. The prenyl group was introduced in the final stages of the synthesis through regioselective Claisen rearrangement. The synthesis has been achieved in 19 steps.

The effects of indigenous fermentation on volatile compound profiles in a Theobroma cacao L, TSH565 clone, resistant to Moniliophtora perniciosa and Phytophthora spp. were evaluated in Southern Brazil. Sixty-three volatile flavor compounds in pulp and 36 in grains were identified by SPME-HS/GC-MS and classified as terpenes, alcohols, esters, ketones and aldehydes, among others. The relative amount of these compounds and their evolution until the end of the fermentation process were assessed in both fresh and fermented grains/pulp masses. -myrcene and -cis-ocimene, among terpenes, were detected in high amounts and are associated to a fine chocolate aroma. The sensory evaluation of chocolates manufactured from the fermented cocoa was performed by trained panelists, which defined 15 sensory descriptors. Chocolates from the TSH565 cultivar were characterized by a rich, fruity, intense cocoa flavor and bitterness, which are valuable sensorial and commercial attributes.

Phenols are common precursors and core structures of a variety of industrial chemicals ranging from pharmaceuticals to polymers. However, the synthesis of site-specifically substituted phenols is challenging, and thus the development of new methods for this purpose would be highly desirable. Reported here is a protocol for palladium-catalyzed ortho-selective alkylation reactions of phenols with primary alcohols by a dearomatization-rearomatization strategy, with water as the sole by-product. Various substituted phenols and primary alcohols were compatible with the standard reaction conditions. The detailed mechanism of this transformation was also investigated.

New 1,3,4-trisubstituted pyrazole derivatives were synthesized and evaluated for their antiplasmodial activity. Compounds 4b, 4c, 7a and 7d were the most potent antiplasmodial agents against P. berghei with percent of suppression ranging from 90 to 100%. They were also screened for their in vitro antimalarial activity against the chloroquine resistant strain P. faldparum, (RKL9). Compound 4c displayed the highest in vitro antimalarial activity; 13-fold higher than standard chloroquine phosphate. Molecular docking of the most active compounds against the wildtype and quadruple mutant pf DHFR-TS structures rationalized the in vitro antimalarial activity. Furthermore, these compounds exhibited reasonable in silico drug-likeness and pharmacokinetic properties. Toxicity studies of the most active compounds revealed that all tested compounds were non-toxic and well-tolerated up to 150 mg/kg via oral route and 75 mg/kg via parentral route. According to RBC hemolysis assay, it was found that compound 7a was the most potent anti-inflammatory and least toxic derivative with IC50 value 71-fold higher than IC50 value related to the antimalarial activity. Moreover, cytotoxicity assessment revealed that compound 4c was the least toxic derivative with IC50 value 70000-fold higher than IC50 value related to the antimalarial activity.

Elicitors play a key role against pathogen infestation, becoming as an alternative to chemical pesticides by the improving secondary metabolites synthesis. Their effect on grape volatile compounds has been little investigated. This field trial aimed to study the foliar application of methyl jasmonate (MeJ), chitosan (CHT), and a yeast extract (YE) on grape volatile compounds by HS-SPME-GC-MS. The results showed that, in general, foliar elicitor application decreased the synthesis of grape volatile compounds. Depending of the treatment, MeJ and CHT showed the lowest total amounts of terpenoids, C-13 norisoprenoids, benzenoids, and esters, together with the highest levels of C6 compounds. YE treatment applied to the grapevines barely affected the synthesis of volatile compounds in grapes. The importance of this work is to add information about the effects of elicitors on grape volatile composition in Tempranillo grapevines.

A palladium-catalyzed 1,2-amino carbonylation of 1,3-dienes with (N-SO2Py)-2-iodoanilines has been developed for the construction of 2,3-dihydroquinolin-4(1H)-one scaffolds. Using benzene-1,3,5-triyl triformate (TFBen) as the CO source under the assistance of the N-SO2Py directing group, the reaction proceeded well to afford various 2,3-dihydroquinolin-4(1H)-ones in good yields (up to 88%). The effect of the directing groups was investigated and control experiments were performed to have a better understanding of the reaction pathway.

Quality Control of 3-Hydroxybenzaldehyde. I found the field of Chemistry very interesting. Saw the article Synthesis, antimicrobial, anticancer and QSAR studies of 1-[4-(substituted phenyl)-2-(substituted phenyl azomethyl)-benzo[b]-[1,4]diazepin-1-yl]-2-substituted phenylaminoethanones published in 2019.0, Reprint Addresses Narasimhan, B (corresponding author), Maharshi Dayanand Univ, Fac Pharmaceut Sci, Rohtak 124001, Haryana, India..

A series of 1-[4-(substituted phenyl)-2-(substituted phenyl azomethyl)-benzo[b]-[1,4]diaze pin-1-yl]-2-substituted phenylaminoethanones (1-17) was synthesized and evaluated in vitro for its antimicrobial and anticancer activities. Results of antimicrobial screening indicated that 1-[4-[4-C hloro-phenyl)-2-[(3-nitro-phenylazo)-methyl]-benzo[b][1,4]diazepin-1-yl]-2-(2-methyl-5-nitro-phenyl amino)-ethanone (16) and 1-[4-(3,4-dimethoxy-phenyl)-2-[(4-nitro-phenylazo)-methyl]-benzo [b][1,4]diazepin-1-yl]-2-(3-nitrophenylamino)-ethanone (17) were found to be the most effective antimicrobial agents. The anticancer screening results indicated that 1-[4-(4-dimethylaminophenyl)-2-(p-tolylazo-methyl)-benzo[b][1,4]diazepin-1-yl]-2-phenyl aminoethanone (1, IC50 = 1.42 mu M/mL against HCT 116 cancer cell lines) was the most potent anticancer agent and was more potent than 5-FU. The results of QSAR studies demonstrated the importance of topological parameters, Kier’s alpha first order shape index (kappa alpha(1)) and valence zero order molecular connectivity index ((0)chi(v)) in describing antimicrobial activity, LUMO and kappa alpha(2) in describing anticancer activity of 1-[4-(substituted phenyl)-2-(substituted phenyl azomethyl)-benzo[b]-[1,4]diazepin-1-yl]-2-substitu ted phenylaminoethanones.

Though concept of oxygen bridged bimetallic catalyst for organic reaction is not well understood. Herein, we have tried to explain the concept by experimental as well as its support by full DFT study. We report here a competent protocol for dehydrogenative oxidation of benzylic alcohol using an oxygen bridged bimetallic CuMoO4 nano catalyst. Careful demonstration reveals that oxidation is not effective either with mono-metallic Cu (II) or Mo(VI); instead combination of both the metals through the oxygen bridge [Cu-O-Mo] unexpectedly and interestingly catalyzed the reaction efficiently. The new concept is strongly supported by computational DFT study. DFT study reveals dehydrogenative oxidation is preferred at copper centre over molybdenum and aromatic benzyl alcohols are greatly stabilised. Interaction barrier energy of monometallic CuO and MoO3 catalyst is much higher than bimetallic CuMoO4. Hydrogen transfer has larger barrier heights for CuO (31.5 kcal/mol) and MoO3 (40.3 kcal/mol) than bimetallic CuMoO4.
