Design, synthesis, and anti-tumor evaluation of novel symmetrical bis-benzimidazoles

A novel symmetrical bis-benzimidazole was designed as DNA minor groove binder. Molecular modeling study showed that it could dock into the minor groove of DNA. Several derivatives were synthesized and confirmed by IR, MS, and 1H NMR. All these novel compounds were screened for cytotoxic activity on SKOV-3, HeLa, and BGC-823 cell lines in vitro. Some compounds showed IC50s in the single-digit micromolar range for cytotoxicity in several tumor cell lines.

A NOVEL CATALYTIC PROCESS FOR THE PRODUCTION OF 3,3', 4,4'-TETRAMINOBIPHENYL

This invention relates to a process for the production of 3,3’, 4,4’-tetraminobiphenyl (TAB) of formula (1) from non-carcinogenic raw materials, employing Suzuki type biaryl coupling as the key step. sMore particularly, it relates to a three steps process for the production of TAB comprising biaryl aryl coupling of 2-nitro-4-bromoacetanilide (NBA) of formula (2) catalyzed by sulfilimine based palladacycles as catalysts followed by the basic hydrolysis of acetyl group and the reduction of nitro groups with conventional reducing agents.

Symmetric bis-benzimidazoles: New sequence-selective DNA-binding molecules

A series of bis-benzimidazole compounds with a head-to-head orientation have been designed as sequence-specific DNA binders; crystallographic analysis of oligonucleotide complexes has been combined with DNase I footprinting to confirm that the predicted optimal site for the core bisbenzimidazole motif is the four-base-pair sequence 5'-AATT; this sequence specificity results in inhibition of transcription at A/T sites and may be responsible for the cytotoxic and antitumour effects shown by these head-to-head bis-benzimidazoles.

Models for intramolecular exchange in organic π-conjugated open-shell systems: A comparison of three non-kekule biphenyldinitrenes

The important effect of connectivity upon the nature of intramolecular exchange coupling of unpaired electrons by the biphenyl group was investigated by cryogenic matrix photolysis of diazide precursors expected to yield biphenyl-3,4′-dinitrene (1), biphenyl-3,3′-dinitrene (2), and biphenyl-4,4′-dinitrene (3). System 1 was predicted by parity-based qualitative models to exhibit a high-spin ground state. By Curie law analysis of its electron spin resonance (ESR) spectrum at cryogenic temperatures in frozen 2-methyltetrahydrofuran solution, 1 was found to be a quintet ground-state dinitrene with zero field splitting (zfs) parameters of |D/hc| = 0.153 cm-1, |E/hc| = 0.003 cm-1. System 2 was predicted to be disjoint with nearly-degenerate high-spin and low-spin states. Cryogenic frozen solution ESR spectroscopy showed no ESR-active dinitrene 2 upon extended photolysis of its appropriate diazide precursor, although the related mononitrene with zfs of |D/hc| = 0.996 cm-1 was clearly visible. We presume that system 2 was produced in this experiment, but that it acts either as a singlet ground-state dinitrene or as a pair of isolated mononitrenes. A biradical ESR spectrum was found for photolysis of the diazide precursor to 3, with zfs of |D/hc| = 0.189 cm-1 and |E/hc| -1. The thermal dependence of this biradical spectrum shows it to be an excited state, consistent with quinonoidal dinitrene 3 having a singlet ground state and a triplet excited state ca. 0.6 kcal/mol higher in energy. The results for dinitrenes 1-3 were compared to related work on dicarbene molecules described by others, and it was found that the dinitrenes and dicarbenes exhibit similar electron exchange coupling behavior.
