A series of analogues of the non-steroidal anti-inflammatory drug (NSAID) sulindac 1 were synthesised tethered to nitric oxide (NO) donating functional groups. Sulindac shows antiproliterative effects against immortal PC3 cell lines. It was previously demonstrated that the effect can be enhanced when tethered to NO releasing groups such as nitrate esters, furoxans and sydnonimines. To explore this approach further, a total of fifty-six sulindac-NO analogues were prepared and they were evaluated as NO-releasing cytotoxic agents against prostate cancer (PCa) cell lines. Compounds 1k and 1n exhibited significant cytotoxic with IC50 values of 6.1 ± 4.1 and 12.1 ± 3.2 μM, respectively, coupled with observed nitric oxide release.
NO donors. Part 18: Bioactive metabolites of GTN and PETN-Synthesis and vasorelaxant properties
Lange, Kathrin,Koenig, Andreas,Roegler, Carolin,Seeling, Andreas,Lehmann, Jochen
experimental part, p. 3141 - 3144 (2010/01/17)
The vasodilators glyceryl trinitrate (GTN) and pentaerythrityl tetranitrate (PETN) are supposed to be degraded in vivo to the lower nitrates PETriN, PEDN, PEMN, 1,2-GDN, 1,3-GDN, 1-GMN, and 2-GMN. We synthesized these bioactive metabolites as reference compounds for pharmacokinetic studies. The use of HPLC-methods for monitoring the stepwise reduction of PETN to lower nitrates and the syntheses of the glyceryl dinitrates proved advantageous. Furthermore, we measured the vasorelaxant properties of all metabolites by performing organ bath experiments with porcine pulmonary arteries. In general, the vasodilator potency increases with the number of nitrate moieties in the compound.

Synthesis of haptens and their protein conjugates for immunological determination of nitrate esters and nitramines
Blackburn, G. Michael,Beadham, Ian G.,Adams, Harry,Hutchinson, Alistair P.,Nicklin, Stephen
, p. 225 - 230 (2007/10/03)
Isosteric, isopolar analogues of the nitrate ester pentaerythritol tetranitrate (PETN) and of the cyclic nitramine sym-cyclotrimethylene trinitramine (RDX) having a spacer arm have been linked to carrier proteins to provide immunologically active peptide conjugates. X-Ray structures of RDX, RDX analogue 10, and hapten 14 are compared to establish their conformational relationships. The Royal Society of Chemistry 2000.

Mayants, A. G.,Pyreseva, K. G.,Gordeichuk, S. S.
, p. 1900 - 1903 (2007/10/02)
The possibility of N-nitration of primary aromatic amines containing SO3H and COOH groups by polynitro compounds C(NO2)4, (O2N)3CC(NO2)3, CH3C(NO2)3, C(NO2)3CH2CH2CN, and C(NO2)3CH2CH2COOCH3 and by polynitroxy compounds C(CH2ONO2)4 and HOCH2C(CH2ONO2)3 was investigated.In the presence of alkaline agents tetranitromethane, hexanitroethane, and pentaerythritol tetranitrate nitrate para- and meta-substituted aromatic amines with the formation of the corresponding nitroamine salts.Ortho-substituted amines do not enter into this reaction.
