Sperm of Fruit Fly Drosophila melanogaster under Space Flight
Int J Mol Sci 2022 Jul 6;23(14):7498.PMID:35886847DOI:10.3390/ijms23147498.
Studies of reproductive function under long-term space flight conditions are of interest in planning the exploration of deep space. Motility, including the use of various inhibitors, cellular respiration, and the content of cytoskeletal proteins were studied, assessing the level of expression of the corresponding genes in spermatozoa of Drosophila melanogaster, which were in space flight conditions for 12 days. The experiment was carried out twice on board the Russian Segment of the International Space Station. Sperm motility speed after space flight, and subsequently 16 h after landing, is reduced relative to the control by 20% (p < 0.05). In comparison with the simulation experiment, we showed that this occurs as a result of the action of overloads and readaptation to the Earth’s gravity. At the same time, cellular respiration, the content of proteins of the respiratory chain, and the expression of their genes do not change. We used kinase inhibitor 6-(Dimethylamino)purine (6-DMAP) and phosphatase inhibitors; 6-DMAP restored the reduced the speed of spermatozoa in the flight group to that of the control. These results can be useful in developing a strategy for protecting reproductive health during the development of other bodies in the solar system.
Mouse and Fly Sperm Motility Changes Differently under Modelling Microgravity
Curr Issues Mol Biol 2021 Jul 5;43(2):590-604.PMID:34287235DOI:10.3390/cimb43020043.
Sperm motility is essential for the natural fertilization process in most animal species. Despite the fact that evolution took place under conditions of constant gravity, the motility of spermatozoa of insects and mammals under microgravity conditions changes in different ways. In this work, an attempt was made to explain this effect. The sperm motility of the fruit fly Drosophila melanogaster and the mouse was evaluated after exposure to a random positioning machine for 6 h. Sodium fluoride was used to inhibit serine/threonine phosphatases, sodium orthovanadate was used to inhibit tyrosine phosphatases, and 6-(Dimethylamino)purine was used to inhibit protein kinases. The results obtained indicate that simulated microgravity leads to an increase in the speed of movement of fly spermatozoa by 30% (p < 0.05), and this effect is blocked by sodium fluoride. In contrast, a 29% (p < 0.05) decrease in the speed of movement of mouse spermatozoa under simulated microgravity is prevented by 6-(Dimethylamino)purine. Moreover, after 6 h of exposure, the content of tubulin cytoskeleton and actin proteins remains at the control level in the spermatozoa of flies and mice. However, the content of the actin-binding protein alpha-actinin in fly sperm decreases by 29% (p < 0.05), while in mouse sperm, the relative content of alpha-actinin1 increases by 94% (p < 0.05) and alpha-actinin4 by 121% (p < 0.05) relative to the control, as determined by 6 simulated microgravity tests. It can be assumed that the effect of simulated microgravity on the motility of mammalian spermatozoa is mediated through the regulation of phosphorylation and that of insects through the regulation of dephosphorylation of motor proteins; moreover, the development of a response to changes in external mechanical conditions has a different time scale.
Synthesis and biological evaluation of 4-purinylpyrrolidine nucleosides
J Med Chem 1991 Sep;34(9):2787-97.PMID:1654429DOI:10.1021/jm00113a017.
The synthesis of several novel carbocyclic purine nucleosides that incorporate a nitrogen in place of carbon 3 of the cyclopentyl moiety are described. These analogues are all derived from the key stereochemically defined intermediate N-(tert-butoxycarbonyl)-O-[(4-methoxyphenyl)diphenylmethyl]-trans- 4- hydroxy-D-prolinol (19), which was accessible in 61.1% overall yield for a five-step sequence starting from cis-4-hydroxy-D-proline. The heterocyclic bases, 6-chloropurine and 2-amino-6-chloropurine, are efficiently introduced onto the pyrrolidine ring via a Mitsunobu-type coupling procedure with triphenylphosphine and diethyl azodicarboxylate. Standard transformations and removal of protecting groups gave the cis-adenine (26), hypoxanthine (27), 2,6-diaminopurine (28), and guanine (29) D-prolinol derivatives. In addition, a related sequence from trans-4-hydroxy-L-proline provided the enantiomeric L-prolinol guanine derivative (36). Lastly, the 6-(Dimethylamino)purine analogue, 37, was coupled to N-(benzyl-oxycarbonyl)-p-methoxy-L-phenylalanine to provide, after deprotection, the novel puromycin-like analogue 39. The analogues 26-29, 36, and 39 were all evaluated for antitumor and, except for 39, for antiviral activity. These compounds failed to appreciably inhibit the growth of P388 mouse leukemia cells in vitro at concentrations up to 100 micrograms/mL. In addition, they did not exhibit noticeable activity against the human immunodeficiency virus or herpes simplex virus type 1 at concentrations as high as 100 microM. The adenine analogue, 26, did, however, prove to be a substrate for adenosine deaminase. It possessed an affinity for the enzyme only 50% less than that of adenosine with a Ki = 85 microM.
Purine nucleoside synthesis, an efficient method employing nucleoside phosphorylases
Biochemistry 1981 Jun 9;20(12):3615-21.PMID:6789872DOI:10.1021/bi00515a048.
An improved method for the enzymatic synthesis of purine nucleosides is described. Pyrimidine nucleosides were used as pentosyl donors and two phosphorylases were used as catalysts. One of the enzymes, either uridine phosphorylase (Urd Pase) or thymidine phosphorylase (dThd Pase), catalyzed the phosphorolysis of the pentosyl donor. The other enzyme, purine nucleoside phosphorylase (PN Pase), catalyzed the synthesis of the product nucleoside by utilizing the pentose 1-phosphate ester generated from the phosphorolysis of the pyrimidine nucleoside. Urd Pase, dThd Pase, and PN Pase were separated from each other in extracts of Escherichia coli by titration with calcium phosphate gel. Each enzyme was further purified by ion-exchange chromatography. Factors that affect the stability of these catalysts were studied. The pH optima for the stability of Urd Pase, dThd Pase, and PN Pase were 7.6, 6.5, and 7.4, respectively. The order of relative heat stability was Urd Pase greater than PN Pase greater than dThd Pase. The stability of each enzyme increased with increasing enzyme concentration. This dependence was strongest with dThd Pase and weakest with Urd Pase. Of the substrates tested, the most potent stabilizers of Urd Pase, dThd Pase, and PN Pase were uridine, 2'-deoxyribose 1-phosphate, and ribose 1-phosphate, respectively. Some general guidelines for optimization of yields are given. In a model reaction, optimal product formation was obtained at low phosphate concentrations. As examples of the efficiency of the method, the 2'-deoxyribonucleoside of 6-(Dimethylamino)purine and the ribonucleoside of 2-amino-6-chloropurine were prepared in yields of 81 and 76%, respectively.
