Activation of Peroxisome Proliferator-Activated Receptor γ (PPARγ) by nitroalkene fatty acids: Importance of nitration position and degree of unsaturation

Nitroalkene fatty acids are potent endogenous ligand activators of PPARγ-dependent transcription. Previous studies with the naturally occurring regioisomers of nitrolinoleic acid revealed that the isomers are not equivalent with respect to PPARγ activation. To gain further insight into the structure-activity relationships between nitroalkenes and PPARγ, we examined additional naturally occurring nitroalkenes derived from oleic acid, 9-nitrooleic acid (E-9-NO2-18:1 [1]) and 10-nitrooleic acid (E-10-NO2-18:1 [2]), and several synthetic nitrated enoic fatty acids of variable carbon chain length, double bonds, and nitration site. At submicromolar concentrations, E-12-NO2 derivatives were considerably more potent than isomers nitrated at carbons 5, 6, 9, 10, and 13, and chain length (16 versus 18) or number of double bonds (1 versus 2) was of little consequence for PPARγ activation. Interestingly, at higher concentrations (>2 μM) the nitrated enoic fatty acids (E-9-NO2-18:1 [1], E-9-NO2-16:1 [3], E-10-NO2-18:1 [2], and E-12-NO 2-18:1 [7]) deviated significantly from the saturable pattern of PPARγ activation observed for nitrated 1,4-dienoic fatty acids (E-9-NO2-18:2, E-10-NO2-18:2, E-12-NO2-18:2, and E-13-NO2-18:2).

A new, low impact and efficient synthesis of ω-nitro esters under solid heterogeneous catalysis

Herein, we report a new, efficient and sustainable synthetic protocol for the preparation of ω-nitro esters starting from cyclic 2-nitro ketones. The method involves the use of polymer bound BEMP and provides the target compounds in excellent yields and low process mass intensity and E-factor values.

COMPOUNDS, METHODS AND FORMULATIONS FOR THE ORAL DELIVERY OF A GLUCAGON LIKE PEPTIDE (GLP)-1 COMPOUND OR AN MELANOCORTIN 4 RECEPTOR (MC4) AGONIST PEPTIDE

The present invention relates to novel compounds, methods, and formulations useful for the oral delivery of a GLP-1 compound or an MC4 agonist peptide.

Amberlyst A 21 as new and efficient surface catalyst for the cleavage of 2-nitrocycloalkanones

Ring cleavage of 2-Nitrocycloalkanones with methanol/Amberlyst A 21 gave methyl ω-nitroalkanoates, O2NCH2(CH2)(n)CO2Me where n = 3-6, 8-10,13, in high yield. Subsequent Nef reaction gave the corresponding ω-oxo compounds which were isolated, in the case of methyl 7-oxoheptanoate and methyl 8-oxooctanoate only, or reduced directly with sodium borohydride to give ω-hydroxyalkanoates. A new formal synthesis of exaltolide (15-pentadecanolide) is also reported.

Pyrrolizidine-3-ones

The present invention provides certain 2,3-didehydro-5-oxopyrrolizidinones and indolizidinones which are useful as lipid-altering and anti-atherosclerotic agents.
