摘要:
A 5(S)-(2′-hydroxyethoxy)-20(S)-camptothecin diasterisomer is described which is a better inhibitor of topoisomerase I than either the diastereoisomeric mixture 5(RS)-(2′-hydroxyethoxy)-20(S)-camptothecin, or the 5(R)-(2′-hydroxyethoxy)-20(S)-camptothecin diastereoisomer. Pharmaceutical compositions of the 5(S)-(2′-hydroxyethoxy)-20(S)-camptothecin diastereoisomer are also described as are methods of using the compound for the inhibition of topoisomerase I and for the treatment of cancer.

摘要:
A method and system for determining channel response is provided. The method for determining a channel frequency response (CFR) in a block transmission system comprises performing an N′ point Fast Fourier Transformation (FFT), where N′ is a function of N and K, and N is approximately equal to the number of sub-carriers in a block, and K depends on the coherence bandwidth of the channel corresponding to the block.
