All representatives of Psammosteus, as opposed to other groups of psammosteids, are also characterized by the reduction in size of mesomeric exoskeletal elements, the lateral scales.
This might come from the strongest mesomeric effect, which produced from the delocalization of the unshared electrons of oxygen throw the furan ring into the [alpha], [beta]-unsaturated carbonyl system to accommodate a negative charge on the oxygen of the carbonyl group Scheme 2, which might make the compound less antibacterial active compared with other substituted [alpha], [beta]-unsaturated carbonyl compounds.
Limited SAR studies of the synthetic compounds revealed that the activity is markedly dependent on the mesomeric and inductive effects of various substituent presents in the phenacyl moiety (Table-1).
Oniscolepis (= Strosipherus) was introduced in the pioneer work of Pander (1856), but still only a few features of this taxon, such as the composition of the exoskeleton of two types of mesomeric elements (or units), tesserae and scales, and the histology of these elements, are known.
The mentioned differences in chemical shift [delta] of phenolic protons are because of the mesomeric effect of 2-oxazoline ring and the effect of hydrogen bond between nitrogen of 2-oxazoline ring and proton of the orthohydroxyl group [52].

This group is positive mesomeric group, and the activity might be due to this effect.
The different parameters which are to be considered in bioisosteric replacements include size, shape (hybridization, bond angles, bond length), electronic arrangement (inductive effect, mesomeric effect, polarizability, charge, dipole), nature of atoms and number of atoms, liphophilicity, hydrophilicity, PKa, inter or intramolecular hydrogen bonding and chemical reactivity (biotransformation etc).
