Novel Route to Functionalized Cyclooctanoids via [5+3] Cycloaddition

Neamine and 2-deoxystreptamine neomycin derivatives exhibit antinociceptive activity in rat models of phasic, incision and neuropathic pain

Objectives To assess the antinociceptive activity of the neomycin derivatives neamine and 2-deoxystreptamine following intraspinal administration in rats. Methods We used the tail-flick test and measured the threshold to mechanical stimulation in models of incisional and neuropathic pain. Key findings The derivatives produced antinociception in the tail-flick test and reduced mechanical allodynia in models of incisional and neuropathic pain. The approximate ED50 in milligrams (confidence limits in parenthesis) in these tests were 1.35 mg (0.61; 2.95), 0.20 mg (0.14; 0.27) and 0.28 mg (0.12; 0.63) for neamine, and 1.05 mg (0.68; 1.60), 0.78 mg (0.776; 0.783) and 0.79 mg (0.46; 1.34) for 2-deoxystreptamine, respectively. Neamine was more potent than 2-deoxystreptamine in the incisional and neuropathic pain models, but they had similar potency in the tail-flick test. Tetra-azidoneamine, a neamine derivative in which free amino groups are replaced with azido groups, did not change the incisional mechanical allodynia. The reduction of incisional allodynia by neamine and 2-deoxystreptamine was transitorily antagonized by intrathecal administration of calcium chloride. Conclusions The intraspinal administration of neamine and 2-deoxystreptamine is antinociceptive in rats. The presence of amino groups in the structure of these derivatives is fundamental to their antinociceptive effect, which may be due to a calcium antagonist activity.

Synthesis and biological evaluation of modified 2-deoxystreptamine dimers

Aminoglycosides are powerful antibiotics, but the emergence of resistant bacterial strains has prompted the search for analogues with better pharmacological profiles. The synthesis of 2-deoxystreptamine (2-DOS) dimers linked by polyamines and analogues based on furylcarbopeptoid skeletons is described. Potent and selective ligands for bacterial 16S rRNA were identified using microarray techniques by determining the affinity of these derivatives toward bacterial and human ribosomal RNAs.

Mechanism of the Formation of Two Epimeric Diamino-hexose Rings of Neomycin B

By using variously tritiated hexoses and Streptomyces fradiae (a neomycin-producer), the mechanism and stereochemistry of the formation of various subunits of neomycin B were investigated.The results of the incorporation of (6RS)-D-glucose into neomycin B followed by specific degradation showed that during the formation of the aminomethyl group of the neosamine B ring one of the 6-3H atoms of the precursor was removed.The 3H remaining at C-6 of the neosamine B ring was shown to be located in the HSi orientation through the isolation of the chiral centre as glycine and the analysis of the latter by using an exchange reaction catalysed by serine hydroxymethyltransferase.These results suggested that, as has been previously shown for neosamine C, the aminomethyl group of neosamine B is formed by an oxidation-transamination process;-CH2OH--> -CHO--> -CH2NH2.D-Glucose was prepared by an unambiguous method and incorporated into neomycin B.The radiochemical data on the various subunits of the antibiotic could be interpreted to suggest that the L-idose configuration at C-5 of the neosamine B ring is produced via an enolisation process involving a carbonyl group at either C-4 or C-6.The involvement of C-4 was then eliminated by feeding experiments in which it was shown that the hydrogen atom at C-4 of D-glucose was undisturbed during the incorporation of this position into the C-4 of neosamine B or C.
