摘要:
Synthetic methods for lactone-containing compounds such as the discodermolides are provided, as are compounds which mimic the chemical and/or biological activity thereof, and methods and intermediates useful in their preparation.
摘要:
2-Hydroxy-3-aminopropylsulfonamides are provided along with methods for synthesizing and using such compounds, and chemical intermediates employed in the synthetic methods.
摘要:
Novel pyrrolinone-based compounds mimic or inhibit the biological and/or chemical activity of peptides, including peptide .beta.-strand conformations. Certain compounds contain functionalized pyrrolinone units in place of one or more amino acids of a target peptide.
摘要:
Milbemycin and avermectin macrolides are synthesized by the cyclized linking of separately synthesized northern and southern hemisphere intermediates. The northern hemisphere intermediate is a spiroketal alkenyl aldehyde, and the southern hemisphere intermediate is an aryl alkenyl phosphine oxide anion.
摘要:
The invention provides for compounds of formula I: wherein Z is absent or (CRARB)nW; each RA and RB is independently (i) H, alkyl, alkenyl, alkynyl, cycloalkyl, heterocycloalkyl, aryl, heteroaryl, aralkyl, heteroaralkyl, haloalkyl, each of which may be optionally substituted; (ii) OH, ORc, NH2, NHRc, NRcRc, SH, S(O)mRc; or (iii) RA and RB together form C(O); W is absent, C(O), C(O)O, C(O)NRcRc, O, S(O)m, or NRcRc; Y is an optionally substituted heterocyclic, optionally substituted heteroaryl, optionally substituted cycloalkyl, optionally substituted aryl, or NRXRY; wherein Rx and Ry are each independently H, alkyl or aryl; X1 is selected from the group consisting of halogen, methyl, and hydroxyl; X2 is a halogen; each Rc is independently alkyl, cycloalkyl, heterocycloalkyl, aryl, heteroaryl, aralkyl, or heteroaralkyl, each of which may be optionally substituted; m is O, 1, or 2; and n is 1, 2, 3, 4, 5, or 6; and pharmaceutically acceptable salts thereof.
摘要:
The present invention is directed to hemi phorboxazole A: and its stereoisomers, as well as derivatives of hemi phorboxazole A of formula I: wherein ring A is aryl or a 5- or 6-membered heteroaryl optionally substituted with one or more of halogen, —OH, or —C1-6alkyl; and R is —CN, a 5- or 6-membered heteroaryl, or halogen; and the pharmaceutically acceptable salt forms thereof, in addition to methods of using these compounds.
摘要:
The present invention is directed to carboxylic acid-containing pharmaceutical compounds where the carboxylic acid moieties have been substituted with cycloalkyl-dione derivatives, as well as tautomers and pharmaceutically acceptable salt forms thereof. These bioisosteric replacements improve the compound's ability to effectively cross the blood brain barrier and result in improved pharmacokinetic, toxicological, and/or safety profiles.
摘要:
The present invention is directed to compounds of formula I: wherein A is n is 0, 1, or 2; m is 0 or 1; R1 is H or C1-6alkyl and R2 is H, C1-6 alkyl, substituted or unsubstituted aryl, or substituted or unsubstituted heteroaryl; and X is O or N; as well as tautomers and pharmaceutically acceptable salt forms thereof. Uses of these compounds are also described.
