Xiong, Wenzhang; Shi, Qiu; Liu, Wenbo H. published the artcile< Simple and Practical Conversion of Benzoic Acids to Phenols at Room Temperature>, Recommanded Product: (E)-Cinnamoyl chloride, the main research area is aryl carboxylic acid chlorobenzoicacid decarboxylative oxygenation; aromatic alc preparation.

Herein, an efficient and practical approach to prepare phenols from benzoic acids via simple organic reagents at room temperature was reported. This approach was compatible with various functional groups and heterocycles and can be easily scaled up. To demonstrate its synthetic utility, bioactive mols. and unsym. hexaarylbenzenes was prepared by leveraging this transformation as strategic steps. Mechanistic investigations suggest that the key migration step involve a free carbocation instead of a radical intermediate. Considering the abundance of benzoic acids and the utility of phenols, it was anticipated that this method will find broad applications in organic synthesis.

Zakharenko, Alexandra L.; Drenichev, Mikhail S.; Dyrkheeva, Nadezhda S.; Ivanov, Georgy A.; Oslovsky, Vladimir E.; Ilina, Ekaterina S.; Chernyshova, Irina A.; Lavrik, Olga I.; Mikhailov, Sergey N. published the artcile< Inhibition of tyrosyl-DNA phosphodiesterase 1 by lipophilic pyrimidine nucleosides>, Name: 1-Chloropyrrolidine-2,5-dione, the main research area is deoxyribonucleic acid repair nucleoside topoisomerase inhibitor; DNA repair; Tdp1 inhibition; nucleosides; topotecan; tyrosyl-DNA phosphodiesterase.

Inhibition of DNA repair enzymes tyrosyl-DNA phosphodiesterase 1 and poly(ADP-ribose) polymerases 1 and 2 in the presence of pyrimidine nucleoside derivatives was studied here. New effective Tdp1 inhibitors were found in a series of nucleoside derivatives possessing 2′, 3′, 5′ -tri-O-benzoyl-d-ribofuranose and 5-substituted uracil moieties and have half-maximal inhibitory concentrations (IC50) in the lower micromolar and submicromolar range. 2′, 3′, 5′-Tri-O-benzoyl-5-iodouridine manifested the strongest inhibitory effect on Tdp1 (IC50 = 0.6μM). A decrease in the number of benzoic acid residues led to a marked decline in the inhibitory activity, and pyrimidine nucleosides lacking lipophilic groups (uridine, 5-fluorouridine, 5-chlorouridine, 5-bromouridine, 5-iodouridine, and ribothymidine) did not cause noticeable inhibition of Tdp1 (IC50 > 50μM). No PARP1/2 inhibitors were found among the studied compounds (residual activity in the presence of 1 mM substances was 50-100%). Several O-benzoylated uridine and cytidine derivatives strengthened the action of topotecan on HeLa cervical cancer cells.

Jr. published the artcile< Fate of 2-chloro-1-(3-ethoxy-4-nitrophenoxy)-4-(trifluoromethyl)benzene (oxyfluorofen) in rats>, Application In Synthesis of 35852-58-5, the main research area is fluoromethylbenzene metabolism rat; ethoxynitrophenoxybenzene metabolism rat; nitrophenoxybenzene metabolism rat; herbicide metabolism rat.

Albino rats were dosed orally with 14C-labeled 2-chloro-1-(3-ethoxy-4-nitrophenoxy)-4-(trifluoromethyl)benzene (I) [42874-03-3] for 7 consecutive days. Only trace amounts of radioactivity (2-4%) were recovered in the urine and tissues. The major route of I elimination was through the feces (∼95%). About 75% of the fecal radioactivity was as unchanged I. Other compounds present in feces were: 5-[2-chloro-4-(trifluoromethyl)phenoxy]-2-nitrophenol [42874-63-5], 4-[2-chloro-4-(trifluoromethyl)phenoxy]-2-ethoxybenzenamine [64378-95-6], N-[4-[2-chloro-4-(trifluoromethyl)phenoxy]-2-ethoxyphenyl]acetamide [64378-96-7], and N-[4-[2-chloro-4-(trifluoromethyl)phenoxy]-2-hydroxyphenyl]acetamide [64378-97-8].

Franquet-Griell, Helena; Medina, Andres; Sans, Carme; Lacorte, Silvia published the artcile< Biological and photochemical degradation of cytostatic drugs under laboratory conditions>, Safety of 2-(Bis(2-chloroethyl)amino)-1,3,2-oxazaphosphinane 2-oxide hydrate, the main research area is biol photochem degradation cytostatic drug water wastewater; Advanced oxidation processes; Biodegradation; Cytostatic drugs; Kinetics; Photolysis.

Cytostatic drugs, used in chemotherapy, have emerged as new environmental contaminants due to their recurrent presence in surface waters and genotoxic effects. Yet, their degradability and environmental fate is largely unknown. The aim was to determine the degradation kinetics of 16 cytostatic drugs, prioritized according to their usage and occurrence in hospital and wastewater treatment plants (WWTP) effluents, through the following laboratory scale processes: hydrolysis, aerobic biodegradation, UV-C photolysis, UV-C/H2O2 and simulated solar radiation. Some drugs were unstable in milli-Q water (vincristine, vinblastine, daunorubicin, doxorubicin and irinotecan); others were photodegraded under UV-C light (melphalan and etoposide) but some others were recalcitrant to biodegradation and/or UV-C, making necessary the use of advanced oxidation processes (AOPs) such as UV-C/H2O2 for complete elimination (cytarabine, ifosfamide and cyclophosphamide). Radiation in a solar box was used to simulate the fate of cytostatic drugs in surface waters under natural radiation and complete removal was not observed for any drug. The degradation process was monitored using liquid chromatog. coupled to high resolution mass spectrometry and pseudo-1st order kinetic degradation constants were calculated This study provides new data on the degradability of cytostatic compounds in water, thus contributing to the existing knowledge on their fate and risk in the environment.
