A family of naturally occurring oligopeptides includes netropsin, distamycin, anthelvencin, kikumycin B, amidinomycin, and norformycin. Netropsin (I) and distamycin (II) express their biological activities by targeting specific sequences of chemical functionalities in the minor groove of DNA. Both netropsin and distamycin can be regarded as polyamide chains in which each α-carbon has been replaced by a five-membered pyrrole ring. The repeat distance in such an augmented polyamide chain is almost the same as the distance from one base pair to the next along the floor of a minor groove within β-DNA. In this paper we report the synthesis of 16-21 cross-linked polyamides containing a thiazole heterocyclic ring bearing the active functionalites NH2, NHCHO, or H. 16 and 17 were synthesized by DCC and HOBt catalyzed reaction of 5 with 14 and 15, while the formylation products 18 and 19 were obtained by coupling the formylated 4-methyl-thiazolated acid 6 with 14 and 15. The deaminated compounds 20 and 21 were obtained by the coupling of 5-trichloroacetyl-4-methylthiazole 7 synthesized from 4-methylthiazole. All the six cross-linked polyamides 16-21 were tested for their DNA gyrase inhibition. The studies have shown these polyamides have better sequence recognition and a greater percentage of inhibition than the corresponding monomers. The compound 17 shows complete inhibition of gyrase at 0.5 μM concentration as compared to the naturally occurring distamycin at 1.0 μM.

[formula: see text] 4'-Bromoacetophenone derivatives which upon excitation can generate monophenyl radicals capable of hydrogen atom abstraction were investigated as photoinducible DNA cleaving agents. Pyrrolecarboxamide-conjugated 4'-bromoacetophenones were synthesized, and their DNA cleaving activities and sequence selectivities were determined.

Novel fatty acyl and phospholipid derivatives of pyrrole polyamide were synthesized. Their cytotoxicity against a cancer cell line of MT-4 cells and those infected by human immunodeficiency virus (HIV) was examined. Although no anti-HIV activity was found, their cytotoxicitty against the cancer cells was significantly enhanced by introducing a lipophilic group into the pyrrole polyamide.
