COMPOSITIONS AND METHODS FOR THERAPY OF PROSTATE CANCER USING DRUG COMBINATIONS TO TARGET POLYAMINE BIOSYNTHESIS AND RELATED PATHWAYS
-
Paragraph 0062, (2016/12/07)
Provided are compositions and methods for treating prostate conditions. The methods involve administering to an individual in need thereof a composition that contains i) an inhibitor of methionine salvage pathway in prostate of the individual and ii) a polyamine analogue. The methods are for use in individuals who have been diagnosed with, or are suspected of having or at risk for developing androgen sensitive prostate cancer (AS-CaP), or Castration recurrent CaP (CR-CaP), or benign prostate hyperplasia (BPH). The disclosure includes use of inhibitors of methylthioadenosine phosphorylase (MTAP), and a polyamine analog that upregulates polyamine catabolism by increasing spermidine/spermine Nl -acetyl transferase (SAT1) activity, such as methylthio-DADMe-Immucillin (MTDIA), andl),N(11)-bisethylnorspermine (BENSpm), respectively. Pharmaceutical formulations that contain a combination of the inhibitor of the methionine salvage pathway and a polyamine analogue are included, as are kits that contain such agents.
Profiling base excision repair glycosylases with synthesized transition state analogs
Chu, Aurea M.,Fettinger, James C.,David, Sheila S.
, p. 4969 - 4972 (2011/10/09)
Two base excision repair glycosylase (BER) transition state (TS) mimics, (3R,4R)-1-benzyl (hydroxymethyl) pyrrolidin-3-ol (1NBn) and (3R,4R)- (hydroxymethyl) pyrrolidin-3-ol (1N), were synthesized using an improved method. Several BER glycosylases that repair oxidized DNA bases, bacterial formamidopyrimdine glycosylase (Fpg), human OG glycosylase (hOGG1) and human Nei-like glycosylase 1 (hNEIL1) exhibit exceptionally high affinity (K d~pM) with DNA duplexes containing the 1NBn and 1N nucleotide. Notably, comparison of the Kd values of both TS mimics relative to an abasic analog (THF) in duplex contexts paired opposite C or A suggest that these DNA repair enzymes use distinctly different mechanisms for damaged base recognition and catalysis despite having overlapping substrate specificities.

A practical synthesis of the purine nucleoside phosphorylase (PNP) inhibitor BCX-4208 (1) was accomplished in three telescoped steps. Mannich condensation of the 4-benzyloxy-9-deazahypoxanthine with (3R,4R)-3-hydroxy-4- (hydroxymethyl)pyrrolidine and formaldehyde followed by removal of the protecting group and crystallization furnished the desired product as a hydrochloride salt in 85% overall yield and 99.8% purity. A scalable synthesis of 9-deazahypoxanthine is also reported. 2009 American Chemical Society.

The title compound (+)-5, required for production of transition state analogue inhibitors of enzymes involved in T-cell-dependent disorders, was synthesized in five steps. A 1,3-dipolar cycloaddition of the nitrone formed from formaldehyde and N-benzylhydroxylamine to diethyl maleate gave the racemic cis-isoxazolidine (±)-7. Reduction of the N-O bond of this compound gave pyrrolidone (±)-8 in excellent yield. A very efficient enzymic resolution of this racemic product led to the title enantiomer (+)-5. This route employs only one chromatographic purification. The Royal Society of Chemistry.
