A benefit of imprinted polymers is the possibility to prepare sorbents with selectivity pre-determined for a particular substance, or group of structural analogues. The application most close to a wider acceptance is probably that of solid phase extraction for clean-up of environmental and biological samples. The technique of molecularly imprinted polymers to solid phase extraction (MISPE) is performance and high selectively, compared with traditional sorbents. In this paper, the preparation and application of MIPs would be reviewed.

The rate of growth of normal human skin fibroblasts was inhibited in a dose related, reversible, fashion by practolol (N-4-(2-hydroxy)-3 (1-methyl)-aminopropoxyphenylacetamine) (ID50 1.35 ± 0.14 x 10-3M), propranolol (1-(isopropylamino)-3(1-naphthyl-oxy)-2-propranolol) (ID50 0.145 ± 0.02 x 10-3M) and paracetamol (N-(4-hydroxyphenyl) acetamide) (ID50 0.85 ± 0.2 x 10-3M). Skin fibroblasts isolated from a psoriasis patient were more sensitive towards practolol (ID50 0.48 ± 0.14 x 10-3M) and propranolol (ID50 0.032 ± 0.002 x 10-3M), but less sensitive towards paracetamol (ID50 1.3 ± 0.07 x 10-3M). In vitro generated metabolites of practolol, using normal or Arochlor 1254-pretreated hamster liver preparations, and structural analogues of practolol had no effect upon the growth of either cell type.

The total synthesis of an isoprenoid-like analogue (2) of octacidomycin (1). a novel oligocarboxylic acid antibiotic, is described. Starting from 3 (Scheme 1) and the tetraethylester of 1,11-dibromoundecane-4,4,8,8,-tetracarboxylic acid (6) as a key compound systematical fragment condensations lead to the pentadeccicarboxylic acid 12 and hence to the 1,3,7,11,15,19,23,27-heptacosane-octacarboxylic acid 2. This contains regularly connected C5- instead of C7-units and shows contracted distances between the acid groups. The newly developed synthesis yields a hitherto unknown type of oligocarboxylic acids and some useful intermediates with one or two terminal vinylic functions (13-15 ).
