摘要:
Methods for treating conditions associated with hyperglycemia, especially Type II diabetes, with novel naphthylsulfonic acids and related compounds. These compounds, as single stereoisomers or mixtures of stereoisomers, or their pharmaceutically acceptable salts, are useful in methods of stimulating the kinase activity of the insulin receptor, enhancing the activation of the insulin receptor by insulin, and stimulating the uptake of glucose into cells. A variety of antidiabetic compounds and pharmaceutical compositions comprising the antidiabetic compounds are also disclosed.

摘要:
Methods and compositions for the measurement of telomere length have application in medical diagnostic, prognostic, and therapeutic procedures. The methods for measuring telomere length include primer extension-based methods and probe-based methods. The primer extension methods involve elongation of telomeric, linker, and/or subtelomeric based primers under conditions such that the telomere serves as a template for primer extension and that the resultant primer extension products can be compared to standards of known length to provide a measure of telomere length. The probe based methods allow for telomere length measurements using DNA from lysed or whole cells and involve hybridizing an excess of probe to all telomeric repeat sequences in the telomere, measuring the amount of bound probe, and correlating the amount of bound probe measured with telomere length.
摘要:
Methods and compositions for treating cancer and other diseases in which inhibition of telomerase activity can ameliorate disease symptoms or prevent or treat the disease relate to compounds that are derivatives of pyrido�b!thiophenes, pyrido�b!furans, pyridine ethers or pyridine thioethers. Such compounds are characterized by the following structure: ##STR1## X.sub.3 is oxygen or sulfur; and the double dashed lines between X.sub.4 and X.sub.5 indicate an optional double bond, which, when present, forms a fused, bicyclic pyrido�b!furan or pyrido�b!thiophene ring system, depending upon whether X.sub.3 is oxygen or sulfur, respectively. When the double bond is not present, the compound is a monocyclic pyridine ether or thioether, again depending upon whether X.sub.3 is oxygen or sulfur. X.sub.4 is --CH.sub.2 R.sub.21 or --CR.sub.21 --, where R.sub.21 is selected from the group consisting of aryl, heteroaryl, aralkyl, heteroaralkyl, alkylcarbonyl, arylcarbonyl, heteroalkylcarbonyl, heteroaralkylcarbonyl, aralkylcarbonyl, aminocarbonyl, alkylaminocarbonyl, arylaminocarbonyl, dialkylaminocarbonyl, diarylarninocarbonyl, arylalkylaminocarbonyl, carboxyl, alkoxycarbonyl, aryloxycarbonyl, sulfo, alkylsulfonyl and arylsulfonyl; and X.sub.5 is hydrogen, alkyl, hydroxyl, alkoxyl, aryloxyl, halogen, cyano, amino, alkylamino, arylamino, dialkylamino, diarylamino, arylalkylamino, aminocarbonyl, alkylaminocarbonyl, arylaminocarbonyl, dialkylaminocarbonyl, diarylaminocarbonyl, arylalkylaminocarbonyl, carboxyl, alkoxycarbonyl, aryloxycarbonyl, sulfo, alkylsulfonyl, arylsulfonyl or --CR.sub.22 -- where R.sub.22 is selected from the group consisting of hydrogen, amino, alkylamino, arylamino, dialkylamino, diarylamino, arylalkylamino, aminocarbonyl, alkylaminocarbonyl, arylaminocarbonyl, dialkylaminocarbonyl, diarylaminocarbonyl, arylalkylaminocarbonyl, hydroxyl, halogen, cyano, carboxyl, alkoxycarbonyl and aryloxycarbonyl. When X.sub.4 is --CR.sub.21 --, X.sub.5 is --CR.sub.22 --, and X.sub.4 and X.sub.5 are joined by the above-mentioned double bond, to form thereby a fused, bicyclic pyrido�b!thiophene (X.sub.3 is sulfur) or pyrido�b!furan (X.sub.3 is oxygen) ring system. When X.sub.4 is --CH.sub.2 R.sub.21, X.sub.5 is not --CR.sub.22 --, thereby forming a pyridine ether (X.sub.3 is oxygen) or thioether (X.sub.3 is sulfur). R.sub.18 and R.sub.19 are selected independently from the group consisting of hydrogen, halogen, hydroxy, aryloxy, alkoxy, lower alkyl, aryl, heteroaryl, aralkyl and heteroaralkyl. R.sub.20 is selected from the group consisting of alkoxymethyl, dialkoxymethyl, arylalkylaminomethyl, arylaminomethyl, alkylaminomethyl, aminomethyl, diarylaminomethyl, dialkylaminomethyl, hydroximinyl, iminyl, aldehyde, alkylcarbonyl, arylcarbonyl, alkyliminyl, aryliminyl, aralkyliminyl, alkoximinyl, aryloximinyl, heterocycleimninyl, alkoxycarbonyl, aryloxycarbonyl, carboxyl, alkene, --HC.dbd.NNHR.sub.23 where R.sub.23 is selected from the group consisting of hydrogen, alkyl, aryl, aralkyl, heterocycle, heterocyclealkyl, and --C(X.sub.6)NHR.sub.24 where X.sub.6 is oxygen or sulfur and R.sub.24 is selected from the group consisting of hydrogen, aryl, arylsulfonyl, aralkyl, heterocycle and heterocyclealkyl.
