- Mesomorphic behaviour of N-benzoyl-N′-aryl thioureas liquid crystalline compounds
-
A series of N-benzoyl-N′-aryl thiourea derivatives bearing alkoxy groups in terminal positions have been prepared and investigated for their potential liquid crystals properties. It was found that only the compounds which have only two alkoxy chains show calamitic mesomorphic behaviour, with nematic, smectic A and C phases being displayed. The type and stability of these mesophases are greatly influenced by the alkyl chain length. Successive introduction of additional alkoxy groups on the benzoyl moiety led to a significant decrease of the clearing points and suppression of the mesogenic character. Using of branched alkyl chain, 2-ethyl-hexyl, instead of normal alkyl group, led to the disappearance of mesogenic behaviour together with the lowering of the clearing temperature. The influence of chain length and number of chains is discussed.

- Synthesis and biological evaluation of 1,4-benzodiazepin-2-ones with antitrypanosomal activity
-
A library of 1,4-benzodiazepines has been synthesized and evaluated against Trypanosoma brucei, a causative parasite of Human African trypanosomiasis. Benzodiazepines possessing a P2- transporter motif were found to have MIC values as low as 0.78 μM.

- The design of non-peptide human Bradykinin B2 receptor antagonists employing the benzodiazepine peptidomimetic scaffold
-
The Bradykinin B2 receptor antagonist HOE 140 (D-Arg-Arg-Pro-Hyp-Gly- Thi-Ser-D-Tic-Oic-Arg) has been used as a template for the de novo design and synthesis of a small number of non-peptide lead compounds based on the 1,4- benzodiazepin-2-one framework. Two of the compounds have been found to exhibit moderate K(i) values of 8.9 and 9.2 μM at the human Bradykinin B2 receptor.
