To improve the water solubility of the anticancer drug candidate LCTA-2034 (A1), we investigated the formation of complexes of this anthrax[2,3-b]furan congener with the solubilizing 2-hydroxypropyl derivative of β-cyclodextrin HP-βCD (Cavitron®). The interaction of A1 with HP-βCD resulted in the inclusion complex A1/HP-βCD in 1:1 stoichiometry. The A1/HP-βCD complex was used to develop a prototype of a lyophilised drug formulation with enhanced (>10-fold) aqueous solubility than A1 and a long-term stability. The use of HP-βCD decreased the acute toxicity of A1 by >30%. The A1/HP-βCD drug formulation as well as A1 in equal doses (5×30mg/kg) to increase the lifespan by up to 140% for mice with i.p. transplanted P388 leukaemia. Furthermore, the A1/HP-βCD formulation demonstrated a significant and reliable antitumor efficacy in a Р388/ADR drug resistant leukaemia and B16/F10 melanoma, proving a perspective of investigations of toxicology, biodistribution and pharmacokinetics.

UI MeSH Term Description Entries
D007928 Lethal Dose 50 The dose amount of poisonous or toxic substance or dose of ionizing radiation required to kill 50% of the tested population. LD50,Dose 50, Lethal
D007938 Leukemia A progressive, malignant disease of the blood-forming organs, characterized by distorted proliferation and development of leukocytes and their precursors in the blood and bone marrow. Leukemias were originally termed acute or chronic based on life expectancy but now are classified according to cellular maturity. Acute leukemias consist of predominately immature cells; chronic leukemias are composed of more mature cells.
