Alkylating derivatives of decathymidylates and methylphosphonate analogs of oligodeoxyribonucleotides (MPAO) were studied for their interaction with cells of Acholeplasma laidlawii PG-8, Mycoplasma capricolum California Kid, M. pneumoniae FH and phytopathogenic strain (St. 118). It is shown that MPAO of octa- and hexadecathymidylates as well as decathymidylates 3'-terminal modified by phenazine and cholesterol groupings are sorbed by mycoplasma cells and can penetrate inside the cells. Efficiency of binding of alkylating derivatives and MPAO with mycoplasma cells depends on interaction time of reagents, their concentration in the reaction mixture and temperature.

UI MeSH Term Description Entries
D009174 Mycoplasma A genus of gram-negative, mostly facultatively anaerobic bacteria in the family MYCOPLASMATACEAE. The cells are bounded by a PLASMA MEMBRANE and lack a true CELL WALL. Its organisms are pathogens found on the MUCOUS MEMBRANES of humans, ANIMALS, and BIRDS.

D009177 Mycoplasma pneumoniae Short filamentous organism of the genus Mycoplasma, which binds firmly to the cells of the respiratory epithelium. It is one of the etiologic agents of non-viral primary atypical pneumonia in man. Eaton Agent
D009838 Oligodeoxyribonucleotides A group of deoxyribonucleotides (up to 12) in which the phosphate residues of each deoxyribonucleotide act as bridges in forming diester linkages between the deoxyribose moieties. Oligodeoxynucleotide,Oligodeoxyribonucleotide,Oligodeoxynucleotides

D000477 Alkylating Agents Highly reactive chemicals that introduce alkyl radicals into biologically active molecules and thereby prevent their proper functioning. Many are used as antineoplastic agents, but most are very toxic, with carcinogenic, mutagenic, teratogenic, and immunosuppressant actions. They have also been used as components in poison gases.

D013329 Structure-Activity Relationship The relationship between the chemical structure of a compound and its biological or pharmacological activity. Compounds are often classed together because they have structural characteristics in common including shape, size, stereochemical arrangement, and distribution of functional groups.
