Autor: V O, Kur'ianov, T A, Chupakhina, O V, Shishkin, S V, Shishkina, V Ia, Chirva

Publikováno v: Bioorganicheskaia khimiia. 34(6)

Regioselective N-beta-glucosamination of various unsubstituted or C4-, C5-, or C6-monosubstituted indolin-2-ones under phase transfer conditions was studied. The regioselectivity was unambiguously proved by (1)H NMR spectroscopy and X-ray analysis. T

Publikováno v: Mikrobiolohichnyi zhurnal (Kiev, Ukraine : 1993). 69(4)

The uninvestigated interferon (IFN)-inducing capacity of glycoside derivatives of N-acetylmuramoyl-L-alanyl-D-isoglutamine (MDP) has been studied. Most MDP glycosides tested in vitro were more active than the reference preparation MDP. Under the in v

[Synthesis and protective anti-infective action of anomeric lipophilic glycosides of N-acetylmuramyl-L-alanyl-D-isoglutamine]

Autor: A E, Zemliakov, V N, Tsikalova, V V, Tsikalov, V Ia, Chirva, E L, Mulik, O V, Kaliuzhin

Publikováno v: Bioorganicheskaia khimiia. 32(4)

Anomeric pairs of alpha- and beta-dodecyl, alpha- and beta-(1-pentylhexyl), and alpha- and beta-cyclododecyl glycosides of N-acetylmuramyl-L-alanyl-D-isoglutamine (MDP) were synthesized. The starting beta-D-glucosaminides were obtained by the oxazoli
