Abstract:
The invention provides a series of -αketoheterocyclic compounds, for example, compounds of formula (I). The compounds can inhibit fatty acid amide hydrolase and can be useful for treatment of malconditions modulated by fatty acid amide hydrolase. The invention further provides methods of making compounds of formula (I), useful intermediates for the preparation of compounds of formula (I), and methods of using compounds of formula (I) and compositions thereof.
Abstract:
Inhibitors of oleamide hydrolase, responsible for the hydrolysis of an endogenous sleep-inducing lipid (1, cis-9-octadecenamide) were designed and synthesized. The most potent inhibitors possess an electrophilic carbonyl group capable of reversibly forming a (thio) hemiacetal or (thio) hemiketal to mimic the transition state of a serine or cysteine protease catalyzed reaction. In particular, the tight binding alpha -keto ethyl ester 8 (1.4 nM) and the trifluoromethyl ketone inhibitor 12 (1.2 nM) were found to have exceptional inhibitory activity. In addition to the inhibitory activity, some of the inhibitors displayed agonist activity which resulted in the induction of sleep in laboratory animals.
Abstract:
An extensive series of CBI analogues of the duocarmycins and CC-1065 exploring substituent effects within the first indole DNA binding subunit is detailed. In general, substitution at the indole C5 position led to cytotoxic potency enhancements that can be ≥ 1000-fold providing simplified analogues containing a single DNA binding subunit that are more potent (IC 50 = 2-3 pM) than CBI-TMI, duocarmycin SA, or CC-1065. The increases in cytotoxicity correlate well with accompanying increases in the rate and efficiency of DNA alkylation. This effect is more pronounced with the CBI versus DSA or CPI based analogues. Moreover, this effect is largely insensitive to the electronic character of the C5 substituent but is sensitive to the size, rigid length, and shape (sp, sp 2 , sp 3 hybridization) of this substituent consistent with expectation that the impact is due simply to its presence.
Abstract:
Synthetically-derived and previously inaccessible modifications of 20'-hydroxy-vinca derivative compounds such as vinblastine, vincristine or vindesine are disclosed that are a stunning 100-fold more active than the natural product (IC 50 's 50-75 pM vs 7 nM, HCT116), and are now accessible as a result of advances in the total synthesis of the natural product. Illustrative new ultra-potent vinblastines bind tubulin with much higher affinity and likely further disrupt the tubulin head-to-tail α/β dimer-dimer interaction by virtue of the strategic placement of an added conformationally well-defined, rigid and extended C20'-urea along the adjacent protein-protein interface. Added molecular complexity was used to markedly enhance target binding and functional biological activity, and represents a general approach to improving the properties of other natural products targeting a protein-protein interaction. A pharmaceutical composition containing an ultra-potent 20'-hydroxy-vinca derivative compound and a method of treating cancerous cells with such a compound are also disclosed.
Abstract:
Certain oxazole ketone compounds are useful as FAAH inhibitors. Such compounds may be used in pharmaceutical compositions and methods for the treatment of disease states, disorders, and conditions mediated by fatty acid amide hydrolase (FAAH) activity. Thus, the compounds may be administered to treat anxiety, pain, inflammation, sleep disorders, eating disorders, or movement disorders (such as MS).
Abstract:
Improved competitive inhibitors of FAAH employ an α-keto heterocyclic pharmacophore and a binding subunit having a ?-unsaturation. The α-keto heterocyclic pharmacophore and a binding subunit are attached to one another, preferably by a hydrocarbon chain. The improvement lies in the use of a heterocyclic pharmacophore selected from oxazoles, oxadiazoles, thiazoles, and thiadiazoles that have alkyl or aryl substituents at their 4 and/or 5 positions. The improved competitive inhibitors of FAAH display enhanced activity over conventional competitive inhibitors of FAAH.
Abstract:
A diprovocim compound that corresponds in structure to structural Formula V is disclosed, wherein A, W, Z, R 1 , R 2 , R 3 and R 4 (when present) are defined within. A diprovocim compound has immune-adjuvant properties on human and mouse cells in culture and on in vivo immunization of mice. A composition containing a diprovocim and a method of using a compound are also disclosed. The immunostimulatory activity of a diprovocim compound is similar to that of LPS, to which there is no apparent structural similarity. A contemplated compound bears no structural similarity to either the TLR1/TLR2 lipoprotein agonists nor to any other synthetic TLR agonist, and is remarkably easy to prepare and synthetically modify.
Abstract:
A TLR-independent adjuvant compound that corresponds in structure to Formula I, below, or its pharmaceutically acceptable salt is disclosed in which X, Y, Z, n, R 1 , R 2 , R 3 , R 4 and W are defined within. Also disclosed are a method of its preparation and use, as well as a pharmaceutical composition containing the same.
Abstract:
The total synthesis and evaluation of key analogs of vancomycin containing single atom changes in the binding pocket are disclosed as well as their peripherally modified, N- (hydrophobe-substituted) derivatives exemplified by a N-4- ( 4 ' -chlorobiphenyl) - methyl derivative and their pharmaceutically acceptable salts are disclosed. Their evaluation indicates the combined pocket and peripherally modified analogs exhibit a remarkable spectrum of antimicrobial activity and truly impressive potencies against both vancomycin-sensitive and -resistant bacteria, and likely benefit from two independent and synergistic mechanisms of action. A pharmaceutical composition containing a contemplated compound or its pharmaceutically acceptable salt is disclosed, as is a method of treating a bacterial infection in a mammal by administering an antibacterial amount of a contemplated compound or its salt as above to an infected mammal in need of treatment.
