• Immunogens for the production of cocaine-hydrolyzing catalytic antibodies

  Methods are described for the rapid synthesis in satisfactory yield of methyl ecgonine phenylphosphonates as analogues of transition states for the hydrolysis of the benzoyl ester of an ecgonine derivative, namely cocaine, and their linking to carrier proteins, for the purpose of using them as immunogens. The resulting immunogens elicit the formation in experimental animals of antibodies able to promote the hydrolysis of cocaine. Both these catalytic anti-cocaine antibodies and the immunogens themselves are potentially useful for the treatment of individuals seeking to avoid the pharmacological effects of cocaine and in diagnostic applications.

  本文介绍了如何以令人满意的产量快速合成甲基蜕皮激素苯基膦酸盐，作为蜕皮激素衍生物（即可卡因）苯甲酰酯水解过渡态的类似物，并将其与载体蛋白连接，以用作免疫原。由此产生的免疫原会在实验动物体内形成能够促进可卡因水解的抗体。这些催化抗可卡因抗体和免疫原本身都有可能用于治疗寻求避免可卡因药理作用的人和诊断应用。
• Anti-Cocaine Catalytic Antibodies:  A Synthetic Approach to Improved Antibody Diversity

  Catalytic antibodies are potential therapeutic agents for drug overdose and addiction, and we previously reported the first such artificial enzymes to degrade cocaine. However, as described herein, these catalytic monoclonal antibodies (Mab's) were found to have nearly identical complementarity-determining regions (CDR's). Such limited diversity among catalytic antibodies of similar specificity has been reported previously and poses a problem since the capacity of any single group of homologous catalytic antibodies to yield one of high activity, whether through repetitive screening of hybridomas or through antibody mutagenesis, is unpredictable. One strategy to increase the diversity of the immune response to an analog would be to vary the tether site of the immunogenic conjugate thereby exposing unique epitopes for immunorecognition. We now report the syntheses of three immunogenic conjugates of a transition-state analog (TSA) of cocaine benzoyl ester hydrolysis which have identical phosphonate monoester core structures but varying tether sites for attachment to carrier protein: TSA 1 at the methyl ester, TSA 2 at the 4'-phenyl position, and TSA 3 at the tropane nitrogen. Mixed phosphonate diester precursors were obtained from phosphonic dichlorides and ecgonine alkyl esters through our 1H-tetrazole catalysis method. We found that all three analogs provided catalytic antibodies that hydrolyze cocaine at the benzoyl ester; the most active catalytic antibody, Mab 15A10, displayed a rate acceleration (k(cat)/k(uncat) = 2.3 x 10(4)) sufficient to commence preclinical studies. On competitive ELISA, all nine catalytic antibodies, regardless of the eliciting antigen, bound TSA 1 with high affinity but four bound TSA 3 poorly and five failed to bind TSA 2 despite the inhibition of all antibodies by free TSA (TSA 4). A comparison of heavy and of light chain CDR's showed four discrete groups with TSA 1 and 3 each yielding two non-overlapping families of catalytic antibodies; TSA 2 yielded one antibody with CDR's nearly identical to those of the largest group of catalytic antibodies elicited by TSA 1. The failure of TSA 2 and TSA 3 to bind to catalytic antibodies derived from alternative immunogenic conjugates demonstrates that the tether sire does limit the catalytic antibodies produced and supports the general strategy of varying the attachment to carrier protein.
