On the other hand, unsubstituted barbituric acid or thiobarbituric acid exhibited better activity than those substituted derivatives, that is, 1,3-dimethyl substituted derivatives.
Additionally, the amine-containing analogue 18 was prepared using the Bruylants reaction as the requisite α-amino nitrile 22 was considered to be more synthetically accessible than the substituted enamine that would be required to use route A (Scheme 1).
Another effect was found that the open-circuit photovoltage (Voc) of the doubly substituted derivative was lower than that of the mono-substituted one.
Disc aggrecan is more highly substituted with keratan sulphate than that found in the deep zone of articular cartilage.
Third, assessment-based incentive schemes are mechanisms that complement rather than substitute for systems that promote parental choice, e.g. vouchers and charter schools.
Our results suggest that the stratum corneum of involved psoriatic skin substitutes is less organized than that of normal skin substitutes.
We substitute,, then, that is,.
It was shown that the VO43− substituted samples presented discharging capacity higher than that of bare non-substituted Nasicon and the reported Ti4+ and Mn2+ doped ones.
In Figure 1, the cell adherence of dNC-PCs on bone substitute materials was better than that of DFCs.
The polymerization of iso-butyl vinyl ether (IBVE) was faster than that of linearly substituted n-butyl vinyl ether (BVE) and less bulky ethyl vinyl ether (EVE).
