The mitogen-activated protein kinase (MAP) kinase 4 (MKK4) was found to be a major regulator of liver regeneration and could be a valuable drug target addressing liver related diseases by restoring its intrinsic regenerative capacity. We report on the synthesis and optimization of novel MKK4 inhibitors following a target-hopping strategy from the FDA-approved BRAFV600E inhibitor PLX4032 (8). Applying an iterative multi-parameter optimization process we carved out essential structural features yielding in compounds with a low nanomolar affinity for MKK4 and excellent selectivity profiles against the main off-targets MKK7 and JNK1, which, upon relevant inhibition, would totally abrogate the pro-regenerative effect of MKK4 inhibition, as well as against the off-targets MAP4K5, ZAK and BRAF with selectivity factors ranging from 40 to 430 for our best-balanced compounds 70 and 73.
Tert -Butyl Hypochlorite Mediated Oxidative Chlorination of S -Alkylisothiourea Salts: Synthesis of Sulfonyl Chlorides
Qiu, Kui,Wang, Rennan
, p. 3186 - 3190 (2015/10/19)
Under neutral conditions, a variety of S-alkylisothiourea salts were smoothly converted into the corresponding sulfonyl chlorides through tert-butyl chlorite mediated oxidative chlorination in good to excellent yields after simple purification. In addition to the environmental and procedural advantages of this method, the neutral conditions potentially make it applicable to substrates that bear acid-sensitive functional groups. For example, the Cbz-protected 2-aminoethanesulfonyl chloride could be synthesized in moderate to good yields under the current neutral conditions, and the acid-sensitive Cbz-protecting group was not affected.

Clean and economic synthesis of alkanesulfonyl chlorides from S-alkyl isothiourea salts via bleach oxidative chlorosulfonation
Yang, Zhanhui,Zhou, Bingnan,Xu, Jiaxi
, p. 225 - 229 (2014/03/21)
A simple procedure for clean and economic synthesis of alkanesulfonyl chlorides via bleach-mediated oxidative chlorosulfonation of S-alkyl isothiourea salts is disclosed. This procedure is environment- and worker-friendly with the advantages of readily accessible materials and reagents, simple and safe operations, easy purification without chromatography, and affords high yields of up to 99%.
Convenient and environment-friendly synthesis of sulfonyl chlorides from S -alkylisothiourea salts via N-chlorosuccinimide chlorosulfonation

, p. 1675 - 1682 (2013/07/27)
A convenient, practical, and environmentally friendly method for the synthesis of sulfonyl chlorides has been developed. Structurally diverse sulfonyl chlorides were synthesized in moderate to excellent yields from S-alkylisothiourea salts, which can be easily prepared from readily accessible alkyl halides or mesylates and inexpensive thiourea, via N-chlorosuccinimide chlorosulfonation. In large-scale syntheses, the byproduct succinimide from 'waste water' can be conveniently converted into the starting reagent N-chlorosuccinimide with sodium hypochlorite (bleach) to make the method sustainable.

Simple synthesis of sulfonyl chlorides from thiol precursors and derivatives by NaClO2-mediated oxidative chlorosulfonation
Yang, Zhanhui,Zheng, Yongpeng,Xu, Jiaxi
, p. 2165 - 2169 (2013/10/22)
A simple method to synthesize diverse sulfonyl chlorides through NaClO 2-mediated oxidative chlorosulfonation of S-alkyl isothiourea salts is presented. The approach features safe operation, environmental friendliness, convenient purification procedures, and delivers high yields of up to 96%. The procedure is also applicable to substrates such as thiols, disulfides, thioacetates, and xanthates. It is a versatile and convenient method for the synthesis of various sulfonyl chlorides from different thiol precursors and derivatives. Georg Thieme Verlag Stuttgart, New York.

N-Sulfonyl homoserine lactones as antagonists of bacterial quorum sensing
Castang, Sandra,Chantegrel, Bernard,Deshayes, Christian,Dolmazon, René,Gouet, Patrice,Haser, Richard,Reverchon, Sylvie,Nasser, William,Hugouvieux-Cotte-Pattat, Nicole,Doutheau, Alain

A series of 11 N-sulfonyl homoserine lactones has been synthesised. Some of them were found to competitively inhibit the action of 3-oxohexanoyl-L- homoserine lactone, the natural inducer of bioluminescence in the bacterium Vibrio fischeri. Molecular modeling suggests a possible explanation based on the prevention of structural rearrangements necessary for the formation of the active dimer of LuxR.
