For your reference: 1. ÎÒÏëÁ˽âÒ»ÏÂÒ»°ãÐÂÒ©¿ª·¢¹ý³ÌÖÐÕâ¸öÊýÖµÔÊÐíµÄµÄ³ß¶ÈÓжà´óÄØ£¿ Based on Lipinski's Rule of Five, log P in −0.4 to +5.6 range will be ideal drug. So your compounds are good. 2. ÎÒÏëÖªµÀÕâÁ½¸öÊýÖµÔÚÆÀ¹ÀÎÒµÄл¯ºÏÎïµÄ¼ÛÖµ·½Ã棬 First, you need understand what is Log P. LogP , partition (P) coefficient , is the ratio of concentrations of a compound in a mixture of two immiscible phases at equilibrium. These coefficients are a measure of the difference in solubility of the compound in these two phases. Normally one of the solvents chosen is water while the second is hydrophobic such as octanol. Hence both the partition and distribution coefficient are measures of how hydrophilic ("water-loving" or hydrophobic ("water-fearing" a chemical substance is. Log P = log (compound in Octanol/ compound in water) So, ĸÌ廯ºÏÎïAµÄLog P=-1.51, is less hydrophobic than »¯ºÏÎïB£¬ Log P=3.21. In another word, »¯ºÏÎïBÊèË®ÐÔÇ¿. 3. ´ú±íʲôÒâÒ壿 In medical practice, partition coefficients are useful for example in estimating distribution of drugs within the body. Hydrophobic drugs with high octanol/water partition coefficients are preferentially distributed to hydrophobic compartments such as lipid bilayers of cells while hydrophilic drugs (low octanol/water partition coefficients) preferentially are found in hydrophilic compartments such as blood serum. So »¯ºÏÎïB may have more distribution in lipid bilayers of cells which may be your target place. (that's only we guess) |
