Protein arginine methyltransferase 1 (PRMT1) catalyses the methylation of substrate arginine by transferring the methyl group from SAM (S-adenosyl-L-methionine), which leads to the formation of S-adenosyl homocysteine (SAH) and methylated arginine. We have shown previously that the Asp84 on PRMT1 could be a potential inhibitor binding site. In the current study, 28 compounds were designed and synthesized that were predicted to bind the Asp84 and substrate arginine sites together. Among them, 6 compounds were identified as potential PRMT1 inhibitors, and showed strong inhibitory effects on cancer cell lines, especially HepG2. The most potent PRMT1 inhibitor, compound 13d, was selected for molecular dynamic simulations to investigate binding poses. Based on the free energy calculations and structural analysis, we predicted that the ethylenediamine group would tightly bind to Asp84, and the trifluoromethyl group should occupy part of substrate arginine binding site, which is consistent with our original goal. Our results show for the first time that PRMT1 inhibitors can target the Asp84 binding site, which will be helpful for future drug discovery studies.

Lithiation of 1-benzyl and 1-p-methoxybenzyltetrazole at the 5-position with n-butyllithium followed by treatment with electrophiles gave functionalized 1-benzylic tetrazoles, which were converted into the 1-unsubstituted derivatives by debenzylation.

The preparation and reactivity of new solid heterocyclic organozinc reagents, namely N -protected (1 H -tetrazol-5-yl)zinc pivalates, as storable solids with appreciably air and moisture stability are reported. They are obtained in high yields from protected 1 H -tetrazoles by de-protonation using the mixed zinc-magnesium base TMPZnCl·Mg(OPiv) 2(abbreviated as TMPZnOPiv; TMP = 2,2,6,6-tetramethylpiperidyl). Subsequent cross-couplings and copper-catalyzed electrophilic aminations using hydroxylamine benzoates give access to functionalized 1 H -tetrazoles while tolerating many functional groups.

A series of 1-substituted 1H-1,2,3,4-tetrazole compounds have been synthesized in good yields from amines, triethyl orthoformate, and sodium azide through the catalyzed reaction with Yb(OTf)3. Some of the 1-substituted 1H-1,2,3,4-tetrazole compounds showed strong phytocidal activity. Wiley-VCH Verlag GmbH & Co. KGaA, 2006.

INTRODUCTION OF SUBSTITUENTS INTO 5-MEMBERED AZA-HETEROAROMATICS
Begtrup, Mikael
, p. 573 - 598 (2007/10/02)
With emphasis on mono- and regio-selectively, methods for introduction of substituents at nitrogen and carbon atoms of 5-membered aza-heteroaromatics have been developed.The methods involve application of activation and of assistant groups for direction and protection.Activation has been achieved by the use of quaternary azolium ions and azol-N-oxides as reactive intermediates.If necessary, the N-oxides were further activated by alkylation or acylation.
