Selective alkylation of βII-tubulin and thioredoxin-1 by structurally related subsets of aryl chloroethylureas leading to either anti-microtubules or redox modulating agents

Aryl chloroethylureas (CEUs) are potent anti-neoplastic agents alkylating specific intracellular proteins such as βII-tubulin. Recently we have identified a new subset of CEU derived from compound 36 that alkylates thioredoxin isoform 1 (Trx-1), inhibits the nuclear translocation of Trx-1, and favors the accumulation of cells in G0/G1 phase. We have evaluated the effects of various substituents and their position on the aromatic ring of a series of derivatives of 36 on (i) the anti-proliferative activity, (ii) the cell cycle progression, (iii) the nuclear translocation of Trx-1, and (iv) their covalent binding to β-tubulin. The same experiments were performed on representative CEU derivatives where the 2-chloroethyl amino moiety is replaced by either an ethyl, a 2-aminooxazolinyl or a 2-chloroacetyl group. On one hand, our results suggest that CEUs substituted on the phenyl ring at position 3 or 4 by cycloalkyl and substituted cycloalkyl or cycloalkoxy groups inhibit the nuclear translocation of Trx-1 and arrest the cell cycle progression in G0/G1. On the other hand, CEUs substituted by a fused aromatic ring, an aliphatic chain, or a fused aliphatic ring are alkylating βII-tubulin but not Trx-1. Beside the expected inactivity of the ethylurea derivatives, none of the modification to the electrophilic moiety led to cross-selectivity of the drugs toward β-tubulin but increased the anti-proliferative activity and resulted in mitigated effects on Trx-1 translocation.

A mild cyclodesulfurization of N-(2-hydroxyethyl)-N′-phenylthioureas to 2-phenylamino-2-oxazolines using TsCl/NaOH

An efficient synthesis of 2-phenylamino-2-oxazolines 3 via cyclodesulfurization of N-(2-hydroxyethyl)-N′-phenylthioureas 2 by a one-pot reaction using p-toluenesulfonyl chloride (TsCl) and NaOH in very good yields is described.

Investigation of the Mitsunobu reaction of N-(2-hydroxyethyl)-N'- phenyl-ureas

The Mitsunobu reaction of N-(2-hydroxyethyl)-ureas 1 using PPh3 and EtO2CN=NCO2Et led to the mixture of N- and O-alkylation products or a single isomer depending on the substrates.

Efficient Cyclodesulfurization of N-(2-Hydroxyethyl)-N′-Arylthioureas to Δ2-Oxazolines Using Superoxide Radical Anion

Δ2-Oxazolines have been synthesized in good yields by the cyclodesulfurization of N-(2-hydroxyethyl)-N′-phenylthioureas with superoxide radical anion (O2-?) at room temperature in anhydrous acetonitrile.

A simple synthesis of Δ2-oxazolines, Δ2-oxazines, Δ2-thiazolines and 2-substituted benzoxazoles

Carboxylic acids react readily at 0° ← + 24°C with amino alcohols, amino mercaptans and o-aminophenols in the presence of triphenylphosphine- or tributylphosphine dichloride (generated in situ from the reaction of the phosphines with hexacholoroethane or CCl4) and triethylamine in acetonitrile to form the corresponding Δ2-oxazolines, Δ2-oxazines, Δ2-thiazolines and 2-substituted benzoxazoles in one reaction step in yields of up to 80%.

TRANSFORMATIONS OF PYRIDINIUMS DERIVED FROM AMINO-ALCOHOLS AND FROM DIAMINES

Pyridiniums derived from amino alcohols cyclise to ethers or rearrange to aldehydes on heating.Monopyridiniums from diamines can be acylated or converted into ureas or thioureas: these products cyclise on heating in solution to give dihydro-thiazoles, -4H-thiazines, -oxazoles, -4H-oxazines, or tetrahydro-3H-thiazepines.

Carboxylic acids react with amino alcohols, amino mercaptans or diamines in the presence of triphenylphosphine, CCl4 and tert. bases to afford in 50-75percent yield the corresponding Δ2-oxazolines, Δ2-oxazines, Δ2-thiazolines and Δ2-imidazolines.
