Use of herbicides in sugarcane in the Sao Paulo state

Sugarcane is one of the main agricultural cultivations of Brazil, and one of the crops in which herbicides are most applied. In the 2017/2018 season, the estimated sugarcane production was 694.54 million tons, with an estimated increase of 0.9% in yield for this season. In order to evaluate the use of herbicides in this crop in the Sao Paulo State during a five-year period, a survey was carried out with sugarcane farmers. The use of herbicides applied alone and in a formulated mixture, according to their mechanism of action, were evaluated from 2010 to 2014. Photosystem II inhibitor herbicides were the most used in this period and the total amount of herbicides of almost all mechanism of action increased from 2010 to 2014, except for photosystem I inhibitors herbicides. The use of formulated mixtures also increased during this period. The area treated with carotenoid biosynthesis and photosystem II inhibitor herbicides was the largest for the control of monocotyledonous species (Poaceae, Cyperaceae and Commelinaceae). In relation to the dicotyledonous species, the area treated with PROTOX inhibitor herbicides was the largest in all evaluated years.

The structural requirements of histone deacetylase inhibitors: C4-modified SAHA analogs display dual HDAC6/HDAC8 selectivity

Histone deacetylase (HDAC) enzymes govern the post-translational acetylation state of lysine residues on protein substrates, leading to regulatory changes in cell function. Due to their role in cancers, HDAC proteins have emerged as promising targets for cancer treatment. Four HDAC inhibitors have been approved as anti-cancer therapeutics, including SAHA (Suberoylanilide hydroxamic acid, Vorinostat, Zolinza). SAHA is a nonselective HDAC inhibitor that targets most of the eleven HDAC isoforms. The nonselectivity of SAHA might account for its clinical side effects, but certainly limits its use as a chemical tool to study cancer-related HDAC cell biology. Herein, the nonselective HDAC inhibitor SAHA was modified at the C4 position of the linker to explore activity and selectivity. Several C4-modified SAHA analogs exhibited dual HDAC6/8 selectivity. Interestingly, (R)-C4-benzyl SAHA displayed 520- to 1300-fold selectivity for HDAC6 and HDAC8 over HDAC1, 2, and 3, with IC50 values of 48 and 27 nM with HDAC6 and 8, respectively. In cellulo testing of the inhibitors was consistent with the observed in vitro selectivity. Docking studies provided a structural rationale for selectivity. The C4-SAHA analogs represent useful chemical tools to understand the role of HDAC6 and HDAC8 in cancer biology and exciting lead compounds for targeting of both HDAC6 and HDAC8 in various cancers.

Direct entry to peptidyl ketones via SmI2-mediated C-C bond formation with readily accessible N-peptidyl oxazolidinones

(Chemical Equation Presented) In this work, a new method for the preparation of peptidyl ketones is presented employing a SmI2/H 2O-mediated coupling of N-peptidyl oxazolidinones with electron-deficient alkenes. The requisite peptide imides were easily prepared by solution-phase peptide synthesis starting from an N-acyl oxazolidinone derivative of an amino acid. Importantly, they could be used directly in the C-C bond-forming step without the need for further functionalization. Coupling of these peptide derivatives with a second peptide possessing an N-terminal acryloyl group leads to ketomethylene isosteres of glycine-containing peptides. This method represents an alternative means for ligating two small peptides through a C-C bond-forming step.

Facile and efficient addition of terminal alkynes to benzotriazole esters: Synthesis of d-erythro-sphingosine using ynones as the key intermediate

From the perspective of synthesis, ynones are compounds of considerable interest because of their occurrence in a wide variety of biologically active molecules and as key synthetic intermediates. In this context, a facile and highly efficient synthesis of ynones was developed based on the high reactivity of benzotriazole esters formed in situ. Lithium acetylides can alkylate various carboxylic acids in yields ranging from 60% to 92%. To determine whether our methodology is useful for synthesising complex and biologically relevant molecules, we synthesise d-erythro-sphingosine in four steps and with 33% overall yield from l-serine.

Synthesis and in vitro pharmacology of novel heterocyclic muscarinic ligands

A set of novel heterocyclic ligands (7a-9a, 7b-9b, and 9c) structurally related to oxotremorine 2 was designed, synthesized, and tested at muscarinic receptor subtypes. In the binding experiments at cloned hm1-5, the presence of the 2-methylimidazole/2-methyl-3-alkylimidazolium moiety in place of the pyrrolidine ring revealed, in derivatives 8a, 8b, and 9c, a moderate selectivity for some receptor subtypes. The functional in vitro assays yielded results that correlated closely to binding data. In general, on passing from agonists bearing the pyrrolidine moiety to their analogues carrying the 2-methylimidazole function, the overall pharmacological efficacy profile is shifted from agonism toward partial agonism. The insertion of the 2-methyl-3-alkylimidazolium moiety advances the effect such that the compounds are pure antagonists. Quite similarly, chiral 3-oxo-Delta 2-isoxazoline (¡À)-10 behaved as a weak antagonist unable to discriminate the different muscarinic receptor subtypes.

Absolute configuration of lactams and oxazolidinones using kinetic resolution catalysts

A simple method for determining the absolute configuration of oxazolidinones, lactams, and their derivatives using kinetic resolution catalysts is described. The optically pure substrates were acylated using the (S)-HBTM and the (R)-HBTM catalyst, and the faster reaction was determined. An empirical mnemonic was developed for the assignment of the absolute configuration based on the fast-reacting catalyst.
