RENEWABLY DERIVED POLYAMIDES AND METHODS OF MAKING THE SAME
-
, (2018/05/23)
Methods of making polyamides from renewable materials, such as natural oils, are generally disclosed herein. In some embodiments, the polyamides are nylon-10. In some such embodiments, nylon-10 is made by polymerizing 10-aminodecanoic acid, or esters thereof. In some further such embodiments, the 10-aminodecanoic acid monomers (or esters thereof) are derived from natural oils via the metathesis of unsaturated fatty acid moieties of the natural oil.

A series of 23 new 1-methyl-2-alkenyl-4(1H)quinolones have been synthesized and evaluated in vitro for their antimycobacterial activities against fast growing species of mycobacteria, such as Mycobacterium fortuitum, M. smegmatis and M. phlei. The compounds displayed good to excellent inhibition of the growth of the mycobacterial test strains with improved antimycobacterial activity compared to the hit compound, evocarpine. The most active compounds, which possessed chain length of 11-13 carbons at position-2 displayed potent inhibitory effects with an MIC value of 1.0 mg/L. In a human diploid embryonic lung cell line, MRC-5 cytotoxicity assay, the alkaloids showed weak to moderate cytotoxic activity. Biological evaluation of these evocarpine analogues on the less pathogenic fast growing strains of mycobacteria showed an interesting antimycobacterial profile and provided significant insight into the structure-activity relationships.

The cyclo-depolymerisation of linear polyundecanoate has been studied in detail. The cyclic oligomers produced were characterised by gel permeation chromatography, 1H NMR spectroscopy and mass spectroscopy in comparison with the corresponding linear oligomers. A sample of the cyclic dimer was isolated and its crystal structure determined. Cyclic oligooctanoates, oligodecanoates and oligododecanoates were prepared similarly. The ring-opening polymerisation of the cyclic oligoundecanoates was briefly investigated.
