title: Antifertility, antibacterial, antifungal and percent disease incidence aspects of macrocyclic complexes of manganese(II).
abstract: Macrocyclic complexes of Mn(II) were synthesized by template condensation using 2,6-diaminopyridine and diethylenetriamine with malonic, succinic, glutaric and adipic acids. The reaction proceeded smoothly to completion. These 16- to 24-membered N(6), but behaving as tetradentate, macrocyclic complexes were characterized by elemental analyses, molecular weight determinations, infrared, electronic, mass and X-ray spectral analyses. The elemental analyses are consistent with the formation of complexes [Mn(N(6)L(n))Cl(2)]. All the complexes are stable and monomeric in nature, as indicated by the molecular weight determinations. The spectral studies confirmed the proposed framework of the new macrocyclic complexes and indicated an octahedral geometry around the central metal atom. The complexes were screened in vitro against a number of pathogenic fungi and bacteria to assess their growth-inhibiting potential. The testicular sperm density, sperm morphology, sperm motility, density of cauda epididymis, spermatozoa and fertility in mating trials and the biochemical parameters of the reproductive organs of the rat were examined and are discussed.
