The present invention provides for compounds, compositions, methods and systems for inhibiting cell growth. More specifically, the present invention provides for methods, compounds and compositions which are capable of inhibiting mitosis in metabolically active cells. Compounds, compositions and methods of the present invention inhibit the activity of a protein involved in the assembly and maintenance of the mitotic spindle. One class of proteins which acts on the mitotic spindle is the family of mitotic kinesins, a subset of the kinesin superfamily.

The new alkaloid komavicine has been isolated from the epigeal part ofNitraria komarovii, and its structure has been established on the basis of spectral characteristics and chemical transformations. The products of the dehydrogenation of nitrarine with selenium and sulfur have been studied. A method has been developed for the dehydrogenation of dihydro and tetrahydro derivatives in the quinolinyl-β-carboline

The new alkaloid komarovicine has been isolated from the epigeal part of the plantNitraria komarovii Iljin et Lava. Itsstructure has been established on the basis of spectral and experimental results and itssynthesis has been performed. A transition has been made to the alkaloids komarovine and komarovidine isolated previously.
