In alternative embodiments the invention provides compositions and methods for ameliorating diseases and conditions having a beta-amyloid component, including Alzheimer's disease (AD), Vascular Dementia (VD), dementia, pre-dementia, Cognitive Dysfunction Syndrome (CDS) and loss of cognition in humans and in non-human animal. In alternative embodiment the invention provides analogs of AB-007 and its acid form E64c (loxistatin), their preparation, and pharmaceutical compositions thereof and methods of making and using same. In alternative embodiments compositions of the invention are deuterated analogs of AB-007 (or E64d) and E64c (or loxistatin). In alternative embodiments compositions of the invention are metabolically blocked forms as compared to AB-007 and loxistatin. In alternative embodiments compositions of the invention are used to ameliorate (including treat, slow, reverse or prevent) a disease or condition which can be ameliorated by partial or complete inhibition of a cysteine protease, e.g., AD, VD, CDS. The invention also provides alternative dosage forms and formulations for AB-007 and loxistatin, and for compounds of this invention, which can be used e.g., to treat AD, VD and CDS, in humans and in non-human animals.
Sphingolipid metabolite mimetics and methods of synthesizing them are provided. The sphingolipid metabolite mimetics are shown to be effective at inducing apoptosis in various types of tumor cells. Further, the sphingolipid metabolite mimetics are shown to be effective at sensitizing multiple types of tumor cells to TRAIL-induced apoptosis. Formulations containing one or more sphingolipid metabolite mimetics and, optionally, one or more cell death receptor agonists are provided. Methods of treating cancer in a subject in need thereof are provided using one or more sphingolipid metabolite mimetics.

hallmark of human cancer. Ceramide analogues thereby represent a new class of anti-cancer agents. We aimed at developing effective and low toxic ceramide analogues and synthesized a new class of ceramide analogues starting from l-threonine. Several analogues exhibit potent cytotoxicity against human cancer cells in vitro with IC50 as low as 4.8 μM. These ceramide analogues decreased xIAP and Bcl-xL level
