7-Substituted Benzothiophenes and 1,2-Benzisothiazoles. Part 2. Chloro and Nitro Derivatives

The 7-chloro and 7-nitro derivatives of benzothiophene and 1,2-benzisothiazole have been prepared from readily available precursors, which for each substituent are common to both ring systems. 7-Chlorobenzothiophene has been obtained from 3-chloro-2-mercaptobenzoic acid via 7-chlorobenzothiophen-3(2H)-one, or from 2,3-dichlorobenzaldehyde, either via beta-(2,3-dichlorophenyl)-alpha-mercaptoacrylic acid (16) or, preferably, via 7-chlorobenzothiophene-2-carboxylic acid.Hexamethylphosphoric triamide is a particularly useful solvent in which to effect the selective nucleophilic replacement of the 2-chloro substituent in 2,3-dichlorobenzaldehyde. 7-Chloro-1,2-benzisothiazole is available by treatment of 3-chloro-2-mercaptobenzaldehyde with chloramine (57percent), or by heating 2,3-dichlorobenzaldehyde with sulphur and aqueous ammonia (46percent). 7-Nitrobenzothiophene has been obtained by treatment of 2-bromo-3-nitrobenzaldehyde with mercaptoacetic acid under alkaline conditions, followed by decarboxylation of the resulting 2-carboxylic acid.Cyclisation of 2-(n- or t-butylthio)-3-nitrobenzaldoxime with polyphosphoric acid gives 7-nitro-1,2-benzisothiazole in high yield. 3-Nitro-2-t-bytylthiobenzaldehyde behaves unexpectedly with chloramine, to give what is believed to be 7-nitro-2-t-butyl-1,2-benzothiazolium chloride (24) (73percent).

Indazole-and indole-5-carboxamides: Selective and reversible monoamine oxidase B inhibitors with subnanomolar potency

Indazole-and indole-carboxamides were discovered as highly potent, selective, competitive, and reversible inhibitors of monoamine oxidase B (MAO-B). The compounds are easily accessible by standard synthetic procedures with high overall yields. The most potent derivatives were N-(3,4- dichlorophenyl)-1-methyl-1H-indazole-5-carboxamide (38a, PSB-1491, IC 50 human MAO-B 0.386 nM, >25000-fold selective versus MAO-A) and N-(3,4-dichlorophenyl)-1H-indole-5-carboxamide (53, PSB-1410, IC50 human MAO-B 0.227 nM, >5700-fold selective versus MAO-A). Replacement of the carboxamide linker with a methanimine spacer leading to (E)-N-(3,4- dichlorophenyl)-1-(1H-indazol-5-yl)methanimine (58) represents a further novel class of highly potent and selective MAO-B inhibitors (IC50 human MAO-B 0.612 nM, >16000-fold selective versus MAO-A). In N-(3,4- difluorophenyl-1H-indazole-5-carboxamide (30, PSB-1434, IC50 human MAO-B 1.59 nM, selectivity versus MAO-A >6000-fold), high potency and selectivity are optimally combined with superior physicochemical properties. Computational docking studies provided insights into the inhibitors’ interaction with the enzyme binding site and a rationale for their high potency despite their small molecular size.

Photochemical Nickel-Catalyzed Reductive Migratory Cross-Coupling of Alkyl Bromides with Aryl Bromides

A novel method to access 1,1-diarylalkanes from readily available, nonactivated alkyl bromides and aryl bromides via visible-light-driven nickel and iridium dual catalysis, wherein diisopropylamine (iPr2NH) is used as the terminal stoichiometric reductant, is reported. Both primary and secondary alkyl bromides can be successfully transformed into the migratory benzylic arylation products with good selectivity. Additionally, this method showcases tolerance toward a wide array of functional groups and the presence of bases.

Reinvestigating Old Pharmacophores: Are 4-Aminoquinolines and Tetraoxanes Potential Two-Stage Antimalarials?

The syntheses and antiplasmodial activities of various substituted aminoquinolines coupled to an adamantane carrier are described. The compounds exhibited pronounced in vitro and in vivo activity against Plasmodium berghei in the Thompson test. Tethering a fluorine atom to the aminoquinoline C(3) position afforded fluoroaminoquinolines that act as intrahepatocytic parasite inhibitors, with compound 25 having an IC50 = 0.31 muM and reducing the liver load in mice by up to 92% at 80 mg/kg dose. Screening our peroxides as inhibitors of liver stage infection revealed that the tetraoxane pharmacophore itself is also an excellent liver stage P. berghei inhibitor (78: IC50 = 0.33 muM). Up to 91% reduction of the parasite liver load in mice was achieved at 100 mg/kg. Examination of tetraoxane 78 against the transgenic 3D7 strain expressing luciferase under a gametocyte-specific promoter revealed its activity against stage IV-V Plasmodium falciparum gametocytes (IC50 = 1.16 ¡À 0.37 muM). To the best of our knowledge, compounds 25 and 78 are the first examples of either an 4-aminoquinoline or a tetraoxane liver stage inhibitors.

Synthesis and cytotoxic activity of lipophilic sulphonamide derivatives of the benzo[b]thiophene 1,1-dioxide

In the search of new compounds with antineoplastic activity, we have analysed the effect of several structural modifications on the nucleus 6-benzo[b]thiophenesulphonamide 1,1-dioxide on its cytotoxic activity on tumour cells. Lipophilic substituents on the sulphonamide group significantly increased the cytoxic activity measured using a panel of human tumour cell lines. Only slight variations on cytotoxicity were obtained when the sulphonamide group occupied the position 5 of the system. The most active compound was the N-4-methoxyphenyl derivative 15, which showed GI50 values of 1-9 nM against HT-29, CCRF-CEM, K-562 and MEL-AC cells and of 200 nM against HTB-54 cells. Free access to the 3-position of the heterocyclic system seems to be required to obtain cytotoxic derivatives. Derivative 15 was also active at the same level of commercial Doxorubicine against cultured normal human lung fibroblasts.
