These compounds may be prepared by reacting an oxime of a 1-formyl colchicine derivative of the general Formula II <FORM:1058417/C2/3> wherein R3 represents a hydrogen atom or the group <FORM:1058417/C2/4> where R1 is as defined above and R4 is an acyl group, and Z is as defined above, with a dehydrating agent to form the corresponding 1-cyano derivative which when Z is alkylthio and R3 is acylamino may, if desired, be hydrolysed to the N-desacyl compound.  The oxime reactants of Formula II may be prepared by the reaction of the corresponding 1-formyl colchicine derivatives with hydroxylamine and said 1-formyl colchicine derivatives may be prepared from the corresponding 1-unsubstituted colchicine derivatives by reaction with 1,1-dichloromethyl methylether in the presence of stannic chloride (see Specifications 977,696 and 1,058,419).  The compounds of Formula I can be used for the treatment of medullary tumours, lymphatic sarcomas, cutaneous neophasias, digestive tumours, and carcinomas in general and may be employed in association with a pharmaceutical carrier or excipient in the form of powders, ointments, tablets or injections.ALSO:Cultivated land is sprayed with aqueous solutions or suspensions of compounds of the general formula <FORM:1058417/C1/1> wherein R represents a hydrogen atom or the group <FORM:1058417/C1/2> where R1 is a hydrogen atom or an alkyl radical and R2 is a hydrogen atom or an acyl radical, and Z represents an alkoxy or alkylthio group, with the restriction that R2 is an acyl radical when Z represents an alkoxy group.  The compounds are stated to modify mitosis and create polyploids.ALSO:Seeds are treated with a colchicine compound of the general formula <FORM:1058417/A1-A3/1> wherein R represents a hydrogen atom or the group <FORM:1058417/A1-A3/2> , where R1 is a hydrogen atom or an alkyl radical and R2 is a hydrogen atom or an acyl radical, preferably containing between 1 and 24 carbon atoms, and Z represents an alkoxy or alkylthio group, with the restriction that R2 is an acyl group when Z represents an alkoxy group, either undiluted or diluted in a solvent or carrier.
