Abstract:
Disclosed herein are novel polyhydroxylated indolizidine and pyrrolizidine derivates and methods for using the same in the treatment of cancer. The present polyhydroxylated indolizidine and pyrrolizidine derivates has the structure of formula (I),
wherein: X is O or b and c are independently an integral of 0 or and 1; R is selected from the group consisting of H, C1-6 alkyl, alkenyl, alkynyl, aryl, heteroaryl, cycloalkyl, cycloalkenyl, aralkyl, aralkenyl, aralkynyl, heteroaralkyl, heteroaralkenyl, beteroaralkynyl, heterocyclyl, alkoxy, aryloxy, and sulfonyl.
Abstract:
Disclosed herein are novel uses of ADMDP stereoisomers or their derivatives for the manufacture of a medicament for treating Pompe disease. Accordingly, the present disclosure provides a method of treating Pompe disease in a subject. The method includes the step of, administering to the subject a therapeutically effective amount of a compound of formula (I), or a salt, an ester or a solvate thereof, wherein R1 and R2 are independently H or alkyl optionally substituted by —NH2 or —OH, so as to ameliorate, alleviate mitigate and/or prevent symptoms associated with the Pompe disease. According to certain embodiments of the present disclosure, the compound of formula (I) may serve a stabilizer of α-glucosidase via preventing its denaturalization of deactivation.
Abstract:
Crystal structure at 2.16 Å resolution of full-length Escherichia coli penicillin-binding protein 1b (PBP1b) in complex with its inhibitor moenomycin, is provided. 3D structures of amino acid residues involved in moenomycin binding and transglycosylation activity are identified. Binding sites for peptidoglycan synthesis inhibitors comprising amino acid residues from transglycosylase (TG), UvrB domain 2 homolog (UB2H) and transmembrane (TM) domains of PBP1b are identified at atomic level resolution. Rational drug design, based on the atomic coordinates, are disclosed. Methods for screening for antibiotics using anisotropic binding and transglycosylase inhibitor assays and novel antibiotics based on the screening assays are provided.
Abstract:
Disclosed herein are novel uses of a polyhydroxylated pyrrolidine for the manufacture of a medicament for treating Fabry disease (FD). Accordingly, the present disclosure provides a method of treating a subject having or suspected of having FD. The method includes the step of, administering to the subject a therapeutically effective amount of a compound of formula (I), a salt, an ester or a solvate thereof, wherein: R1 is H, or C1-3 amine optionally substituted with —COR2; R2 is alkyl or alkene optionally substituted with cycloalkyl or phenyl having at least one substituent selected from the group consisting of, halo, alkyl, haloalkyl, and alkoxyl; so as to ameliorate, alleviate mitigate and/or prevent symptoms associated with the FD. According to preferred embodiments of the present disclosure, the compound of formula (I) is a chaperon of a mutated human lysosomal α-galactosidase A (α-Gal A).
