Synthesis of an azide-bearing N-mustard analogue of S-adenosyl-L-methionine
Mai, Van,Comstock, Lindsay R.
, p. 10319 - 10324 (2011)
The synthesis of an azide-bearing N-mustard S-adenosyl-L-methionine (SAM) analogue, 8-azido-5′-(diaminobutyric acid)-N-iodoethyl-5′- deoxyadenosine, has been accomplished in 10 steps from commercially available 2′,3′-isopropylidene adenosine. Critical to this success was executing C8 azidation prior to derivatizing the 5′-position of the ribose sugar and the late stage alkylation of the 5′ amino group with bromoethanol, which was necessitated by the reactivity of the aryl azide moiety. The azide-bearing N-mustard is envisioned as a useful biochemical tool by which to probe DNA and protein methylation patterns (Figure presented).
Efficient Synthesis of Azide-Bearing Cofactor Mimics
Comstock, Lindsay R.,Rajski, Scott R.
, p. 1425 - 1428 (2004)
8-Azido-5′-aziridmo-5′-deoxyadenosine (6), a novel cofactor mimic, was synthesized in nine steps from commercially available 2′,3′-isopropylideneadenosine in ~4% overall yield. Crucial to this success was a very unorthodox phthalimide cleavage procedure, C8 azidation prior to aziridination and late stage alkylation of the 5′ amino group with iodoethanol necessitated by the high degree of lability endowed by the aryl azide moiety. Aziridine 6 is envisioned as a useful biochemical tool by which to probe DNA and protein methylation patterns.

Liu, Qing,Cai, Xiaoqing,Yang, Dehua,Chen, Yi,Wang, Yafang,Shao, Liming,Wang, Ming-Wei
, p. 4579 - 4594 (2017/10/05)
A series of cycloalkyl substituted analogues of the natural product sinefungin lacking the amino-acid moiety was designed and synthesized. Two stereoisomers (6-R and 6-S) were separated and their bioactivities examined against EHMT1/2. Of which, compound 14d showed an inhibitory activity against EHMT1/2 (88.9%, IC50 = 21.8 μM for EHMT1 and 77.6%, IC50 = 39.6 μM for EHMT2, respectively) similar to that of sinefungin (100.0%, IC50 = 28.4 μM for EHMT1 and 79.5%, IC50 = 30.1 μM for EHMT2, respectively). Further studies against other methyltransferases such as PRMT1 showed no activity except that 12d displayed about 20% inhibition.
Synthesis and evaluation of adenosine containing 3-arylfuran-2(5H)-ones as tyrosyl-tRNA synthetase inhibitors
Wei, Wei,Liu, Qi,Li, Zhen-Zhen,Shi, Wei-Kang,Fu, Xing,Liu, Jia,Zhu, Xuan,Wang, Xiao-Cong,Xu, Ning,Li, Teng-Fei,Jiang, Fu-Rui,Xiao, Zhu-Ping,Zhu, Hai-Liang

Tyrosyl-tRNA synthetase (TyrRS) is an aminoacyl-tRNA synthetase family protein that possesses an essential role in bacterial protein synthesis. The synthesis, structure-activity relationship, and evolution of a novel series of adenosine-containing 3-arylfuran-2(5H)-ones as TyrRS inhibitors are described. Advanced compound d3 from this series exhibited excellent affinity for TyrRS with IC50 of 0.61?±?0.04?μM. Bacterial growth inhibition assays demonstrated that d3 showed submicromolar antibacterial potency against Escherichia coli and Pseudomonas aeruginosa, and compared to the marketed antibiotics ciprofloxacin.

SELECTIVE INHIBITORS OF HISTONE METHYLTRANSFERASE DOT1L
-
, (2014/04/18)
Structure and mechanism based design was used to design potent ribose containing inhibitors of DOT1L with IC50 values as low as 38 nM. These ribose containing inhibitors exhibit only weak or no activities against four other representative histone lysine and arginine methyltransferases, G9a, SUV39H1, PRMT1 and CARM1.
Parallel solution-phase synthesis of an adenosine antibiotic analog library
Moukha-Chafiq, Omar,Reynolds, Robert C.
supporting information, p. 147 - 152 (2013/04/23)
A library of eighty one adenosine antibiotic analogs was prepared under the Pilot Scale Library Program of the NIH Roadmap initiative from 5′-amino-5′-deoxy-2′,3′-O-isopropylidene-adenosine 3. Diverse aldehyde, sulfonyl chloride and carboxylic acid reactant sets were condensed to 3, in solution-phase fashion, leading after acid-mediated hydrolysis to the targeted compounds in good yields and high purity. No marked antituberculosis or anticancer activity was noted on preliminary cellular testing, but these nucleoside analogs should be useful candidates for other types of biological activity.
