    • Immunoglobulin conjugates are formed by reaction of an antineoplastic indole-dihydroindole vinca alkaloid containing a hydrazide group attached at C-3 or C-4 with an oxidized IgG antibody having unusually high carbo­hydrate content, and are of the formula
      wherein R² is H, CH₃ or CHO; when R⁴ and R⁵ are taken singly, R⁵ is H, and one of R³ and R⁴ is ethyl and the other is H or OH; when R⁴ and R⁵ are taken together with the carbons to which they are attached, they form an oxirane ring in which case R³ is ethyl; R is NHN=,
