Cytotoxic activity and QSAR of N,N′-diarylalkanediamides
摘要:
The one- and two-step syntheses of N,N'-(dinitrophenyl)alkanediamides and N,N'-(diaminophenyl)alkanediamides from 4-nitroaniline were carried out. These compounds were subjected to cytotoxic evaluation against different tumoural cell lines. A QSAR analysis for the aminated series, introducing a QSAR descriptor (DCL) designed herein for groove binders, reveals that the activity in the K562 cell line is related to the charge, polarisability, volume and length of the molecules.

The preparation of N,N'-diarylalkanediamides from the respective aliphatic dicarboxylic acids and 4-nitroaniline via microwave-prompted reactions is presented. The most positive effect of microwave irradiation was observed for N,N'-bis(4-nitrophenyl)butanediamide. Anion binding studies on the obtained diamides were carried out in DMSO and acetonitrile using UV-vis and H-1 NMR spectroscopy. A mechanism for selective fluoride recognition by N,N'-bis(4-nitrophenyl)butanediamide in DMSO is proposed. (C) 2012 Elsevier Ltd. All rights reserved.

There is provided a compound which is a histone deacetylase (HDAC) inhibitor, or a pharmaceutically acceptable ester, amide, solvate or salt thereof, for use in: (I) treating or preventing a pathological condition associated with excess fibrin deposition and/or thrombus formation; and/or (II) potentiating the degradation of fibrin deposits and preventing such deposits associated with pathological conditions or which may lead to such conditions, wherein the HDAC inhibitor, and the dose thereof, is as described in the description. There is also provided valproic acid, or a pharmaceutically acceptable salt thereof, for use in improving or normalizing endogenous fibrinolysis impaired by local or systemic inflammation.
