Drugs representative of the three modes of action presently recognized have been selected: those which increase oxygen affinity (potassium cyanate); those which inhibit hemoglobin polymerization (butylurea); membrane-active compounds.

Pretreatment of mice with potassium cyanate for 15 days resulted in a significant increase in hemoglobin-oxygen affinity (decrease in P 50) and a significant protection against hypoxic hypoxia-induced lethality.

Modification of blood oxygen affinity was achieved both by 2,3-diphosphoglycerate depletion, accomplished by exposure of animals to CO (2) and by exchange transfusion with blood exposed to bisulfite or stored in acid citrate dextrose, and by carbamylation of hemoglobin, produced by exchange transfusion of blood incubated with potassium cyanate.

Solubility determination (Csat) of deoxy hemoglobin S gels demonstrated that HN2 markedly inhibited the polymerization of HbS, was significantly more effective than potassium cyanate, and is among the most potent anti-sickling agents thus far reported.

Reviewing the reaction of potassium cyanate, an antisickling agent, with alpha-amino groups of hemoglobin, it was found that the reaction was a slow process and requires a large excess of the reagent.

The prevention of sickling is a function of the amount of [(14) C] cyanate incorporated into acidprecipitable protein (0.1-1.0 mol of cyanate per mol of hemoglobin).

These tests included (1) the determination of the solubility of deoxyhemoglobin S or Csat, (2) evaluation of sickling in whole SS blood at various pO2s, (3) measurement of the oxygen affinity of hemoglobin and blood, and (4) examination of red cell indices and morphology.
