  • Patent number: 6541672
    Abstract: The invention deals with the derivatives of benzilidine having basic formula as follows (I): wherein X can be cyclohexanone, cyclopentanone, or acetone, while Y and Z can be either electron withdrawing, electron donating or steric group. Y may or may not be the same with Z. Methyl, ethyl, methoxy group or halogen were prefered in the experiment. The benzilidine cyclohexanone, benzilidine cyclopentanone, and benzilidine acetone derivates were found to be novel compounds showing anti-bacterial, antioxidant, and anti-inflammatory activities that enable them to be used for drug.

  • Patent number: 5010095
    Abstract: N-(2-substituted alkyl)-N'[(imidazole-4-yl)alkylguanidines are provided by the reaction of a primary amine with benzoylisothiocyante to a benzoylthiourea derivative, followed by hydrolysis of this derivative to form the corresponding thiourea, converting this thiourea with methyliodide into an isothiourea and producing the desired compound by reaction of the isothiourea with aminopropylimidazole or aminoethylimidazole. The compound can be converted into an acid addition salt or the free compound obtained from such salt. The compounds are useful as the active ingredient in pharmaceutical compositions for the treatment of congestion, heart failure and some allergic conditions.
