When chlorophyll, together with certain other amphiphilic substances, is adsorbed to particles of polyethylene plasticized by incorporation of tetradecane, it is maintained in monomeric or oligomeric forms with characteristic absorption and fluorescence spectra. This work describes the properties of chlorophyll a on such particles in the presence of the three isomeric N-pyridylmyristamides, and of the similarly shaped but not basic compound myristanilide, in an effort to ascertain the structural factors governing associations of these species. Absorption and fluorescence spectra at room temperature are resolved into minimal sets of Gaussian components, and relations and fluorescence spectra at room temperature are resolved into minimal sets of Gaussian components, and relations between the component sets are proposed. The positions of the component bands and their relative abundance are characteristic of the amide used. The 3- and 4-pyridyl isomers bind more strongly to chlorophyll, probably by ligation of the pyridine nitrogen to Mg of the pigment.

The excellent surface catalytic potential of Fe3O4-OSO3H is utilized in the synthesis of symmetrically and unsymmetrically substituted urea derivatives via transamidation reactions. The scope of the surface catalysis is further extended in transamidation reactions of cyclic and acyclic amide derivatives, and in the amidation of fatty acids. In both transamidation and amidation reactions, the catalyst is reusable up to five times without significant loss in its activity.

A series of esters and amides of myristic acid was synthesized and tested in vitro for antibacterial activity against Gram-positive and Gram-negative bacteria. All the compounds showed activity comparable to that of the standard drug, ciprofloxacin. The structural characteristics governing antibacterial activity of myristic acid derivatives was studied using QSAR methodology. The results showed that the antibacterial activity could be modeled using the topological descriptor, valence molecular connectivity index. The predictive ability of the models was cross-validated by construction of a test set. The low residual activity and high cross-validated r2 values ( rcv2 ) observed indicated the predictive ability of the developed QSAR models.
