Differential scanning calorimetric studies on the thermotropic phase behavior of dry and hydrated forms of N-acyltyramines

Structure, Self-Assembly, and Phase Behavior of Neuroactive N-Acyl GABAs: Doxorubicin Encapsulation in NPGABA/DPPC Liposomes and Release Studies

“…Such odd–even alternation in the d spacings was reported earlier in N -acyl-β-alanines, which are structural homologues of NAGABAs (Figure S6). In contrast, odd–even alternation of d spacings in N -acyl serinols is reversed, with even chain length NASOHs having larger d spacing than odd chain length NASOHs . Except for the short chain length (C8 and C9) compounds, the d spacings of the NAGABAs exhibit a linear dependence on the chain length independent of odd and even chain length series with slopes of 2.383 and 2.127 Å/CH 2 , respectively, which correspond to increments of 1.192 and 1.064 Å per additional CH 2 moiety, respectively (Figure C).…”

“…45 Interestingly, for N-acyl L-alanines, 33 hydrated N-acyltaurines, 46 and N-acylserinols, 47 the odd chain length molecules exhibit ΔH t and ΔS t values that are higher than those of the even chain length amphiphiles. Even chain length N-acyl tyramines also showed a linear dependence of ΔH t and ΔS t on acyl chain length, 48 although studies on odd chain length compounds are lacking in this case.…”

While similar odd−even alternation was observed in NABAs that are homologues of NAGABAs containing one fewer CH 2 unit in the headgroup, 27 it was not seen in NAGs (Figure S6B), which are shorter by two CH 2 units in the headgroup.…”

Analytical developments in the synergism of copper particles and cysteine: a review

“…A new class of multifunctional lipid effectors in the cannabinoid-vanilloid system called N -acyl dopamine was considered to have a precursor in the form of NLTA, a sort of fatty acid amide. 164 Another AA was added for selectivity assessment, but cysteine was the first one that induced a color shift in the CuNAPs from brown-olive green at the μM level. The absorbance peak of CuNAPs decreased with the increase in [cyst] and the R 2 value was 0.994.…”
