DECITABINE ANALOGS FOR IMMUNOLOGICAL AND ONCOLOGICAL THERAPY

Page/Page column 42-43, (2022/02/28)
Novel N44-substituted decitabine analogs are disclosed that exhibit promising in vitro and in vivo therapeutic activity. These novel compounds were shown to be resistant to deamination via cytidine deaminase (CDA) metabolism and provide a unique pharmacokinetic profile versus decitabine, while retaining the ability to induce DNA demethylation in target cells. These novel compounds can be used for treating hematological cancers, as well for new therapeutic interventions, including bacterial or viral pneumonia, acute respiratory distress syndrome, pulmonary fibrosis, transplantation and checkpoint inhibitor-induced adverse events, including pneumonitis.

(Figure presented) The cross coupling of the C-OMe bond adjacent to a nitrogen atom in dialkoxy-N,N-dialkylmethanamines with terminal alkynes was efficiently approached in the presence of copper catalyst under mild conditions to give 3-amino-1,4-diynes in good yields. The reaction is promoted by phosphine ligands and the chemistry provides a simple and efficient route to 3-amino-1,4-diynes. Importantly, the Michael addition occurred with as-prepared 3-amino-1,4-diynes to give the useful Michael-adducts containing tert-alkylamines in a very convenient way. Further studies revealed that (E)-1,5-diarylpent-1-en-4-yn-3-one was formed through the rearrangement by using the neutral alumina column, and the corresponding imine 2-(1,5-diphenylpent-2- en-4-ynylideneamino)ethanol was obtained in the presence of AgOTf.

It is shown that the heptalene-4,5-dicarboxylates 5 react with their Me group at C(1) with N,N-dimethylformamide dimethyl acetal or other acetals of this type in N,N-dimethylformamide (DMF) to give the corresponding 1-[(E)-2-(N,N-dialkylamino)ethenyl]-sub

New C-(N,N-dialkylamino)phosphaalkenes were synthesized by the reaction of phenylphosphine with amidacetals.Such compounds were also synthesized by the reaction of bis(trimethylsilyl)phosphine with amidacetals.
1H Nuclear Magnetic Resonance Study of the Kinetics of the Reaction of N,N-Dialkylformamide Dimethyl Acetals with Secondary Amines

, p. 993 - 996 (2007/10/02)
Rate constants and activation parameters (ΔG, ΔH, ΔS) for the reactions of N,N-dialkylformamide dimethyl acetals with four secondary amines have been estimated by 1H n.m.r. spectroscopy.The reactions are reversible and obey a second-order kinetic equation.Substitution of one methoxy group of the amide acetal by the amine entity is found to give ester aminals which are subject to decomposition (ΔG 92-103 kJ mol-1).A transamination reaction yields a new amide acetal at higher temperatures (ΔG 115 kJ mol-1).On the basis of the kinetic data, the mechanism of these reactions is discussed.
