Agave atrovirens is an undervalued and non-commercially-exploded agave specie, however this plant might be a source of compounds with biological activity. In this work, we evaluated three samples obtained from the leaves of this plant (Crude Extract (CE), Total Extract (TE) and Butanolic Extract (BE)). In order to make a partial chemical characterization and identified potential bioactive compounds, these samples were analyzed as hydrolyzed (Hexane-Ethyl acetate (HAE-SF) or Methanol (MeOH-SF) soluble fractions) or non-hydrolyzed samples by GC-MS and HPLC-MS-TOF. Presence of carboxylic and fatty acids, n-alkanes, phenolics as well as steroidal saponins and sapogenins were found in three extracts, however, their presence was more remarkable in BE. A gitogenin glycoside was the compound that possessed the most abundant [M+H]+ ion in all the non-hydrolyzed extracts, while the aglycone gitogenin was the most abundant ion in the hydrolyzed extracts. The type of compounds found in the extracts of A. atrovirens, confirms its potential as a source of bioactive phytochemicals like saponins and sapogenins.

A copper-catalyzed intermolecular oxidative homocoupling of indoles has been developed for the direct construction of valuable C3-C3 biindolyl scaffolds. Using this protocol, 3,3?-bisindolin-2-ones are obtained in good yields and with excellent chemo-and regioselectivity. The methodology shows good functional group tolerance, allows the use of easily available inexpensive precursors, has simple operation, and can be performed under mild reaction conditions. From a retrosynthetic point of view, the strategic formation of a C-C bond via C(sp3-H)/C(sp2-H) dehydrogenative coupling may be useful in indole-derived pharmaceuticals and natural products. Upon screening HepG-2, SCG-7901, MDA-MB-468, MDA-MB-435 and Ishikawa cancer cell lines, compound 2s exhibited a good inhibitory effect against HepG-2 at 10.49 ± 0.41 muM in vitro antitumor activities.

Oxidation of benzyl alcohol and some ortho-, meta- and para-monosubstituted ones by quinolinium fluorochromate (QFC) in dimethyl sulphoxide (DMSO) leads to the formation of corresponding banzaldehydes. The reaction is first order each in both QFC and the alcohol. The reaction is promoted by hydrogen ions; the hydrogen-ion dependence has the form kobs= a + b [H+]. Oxidation of alpha,alpha-dideuteriobenzyl alcohol (PhCD2OH) has exhibited a substantial primary kinetic isotope effect. The reaction has been studied in nineteen organic solvents and the effect of solvent analysed using Taft’s and Swain’s multi-parametric equations. The rates of oxidation of para- and meta-substituted benzyl alcohols have been correlated in terms of Charton’s triparametric LDR equation, whereas the oxidation of ortho-substituted benzyl alcohols with tetraparametric LDRS equation. The oxidation of para-substituted benzyl alcohols is more susceptible to the delocalization effect than that of ortho- and meta-substituted compounds, which display a greater dependence on the field effect. The positive value of eta suggests the presence of an electron-deficient reaction centre in the rate-determining step. The reaction is subjected to steric acceleration by the ortho-substituents. A suitable mechanism has been proposed.
