From COX-2 inhibitor nimesulide to potent anti-cancer agent: Synthesis, in vitro, in vivo and pharmacokinetic evaluation

Cyclooxygenase-2 (COX-2) inhibitor nimesulide inhibits the proliferation of various types of cancer cells mainly via COX-2 independent mechanisms, which makes it a good lead compound for anti-cancer drug development. In the presented study, a series of new nimesulide analogs were synthesized based on the structure-function analysis generated previously. Some of them displayed very potent anti-cancer activity with IC50s around 100 nM-200 nM to inhibit SKBR-3 breast cancer cell growth. CSUOH0901 (NSC751382) from the compound library also inhibits the growth of the 60 cancer cell lines used at National Cancer Institute Developmental therapeutics Program (NCIDTP) with IC50s around 100 nM-500 nM. Intraperitoneal injection with a dosage of 5 mg/kg/d of CSUOH0901 to nude mice suppresses HT29 colorectal xenograft growth. Pharmacokinetic studies demonstrate the good bioavailability of the compound.

Synthesis of 1,1?-ferrocene diformates bearing isoxazole moiety and preliminarily cytotoxicity to A549, HCT116 and MCF-7 cell lines

Background: Ferrocene is a potential pharmacophore for drug design and drug discovery. Methods: Based on our previous good achievements (Med. Chem. commun., 2014,7,968-972), nineteen novel structures of 1,1?-ferrocene diformates bearing isoxazole moiety (3a-3s) were firstly synthesized in the current work and characterized by 1H NMR, 13C NMR, ESI-MS. Then, their cytotoxicity to A549, HCT116 and MCF-7 cell lines was evaluated using the MTT method. Results: The results showed that most compounds exhibited higher potent cytotoxicity to A549, HCT116 and MCF-7 cell lines. Conclusion: Especially, 3b, 3h, 3k, 3l, 3m, 3n, 3o, 3p and 3s simultaneously exhibited stronger inhibitory activity towards A549, HCT116 and MCF-7 cell lines than that of the reference drug cisplatin, which can be regarded as very promising metal-based lead compounds for anticancer agents.

Solvent effect on the debromination/dehydrobromination of bromo-damascone

The dehydrogenative synthesis of beta-damascenone from beta-damascone via the related allyl bromide intermediate was studied in depth. The requisite dehydrobromination thereof was found strongly solvent system dependent. Under respective conditions, the product was identified as dehydrogenation-derived a, 4-alkoxy-derived b and 4-oxo-derived c, accordingly. In addition, the conversion from b to a was successfully accomplished, thereby offering an alternative access (with one step more) to reach beta-damascenone. Copyright

FMNH2-dependent monooxygenases initiate catabolism of sulfonamides in Microbacterium sp. strain BR1 subsisting on sulfonamide antibiotics

We report a cluster of genes encoding two monooxygenases (SadA and SadB) and one FMN reductase (SadC) that enable Microbacterium sp. strain BR1 and other Actinomycetes to inactivate sulfonamide antibiotics. Our results show that SadA and SadC are responsible for the initial attack of sulfonamide molecules resulting in the release of 4-aminophenol. The latter is further transformed into 1,2,4-trihydroxybenzene by SadB and SadC prior to mineralization and concomitant production of biomass. As the degradation products lack antibiotic activity, the presence of SadA will result in an alleviated bacteriostatic effect of sulfonamides. In addition to the relief from antibiotic stress this bacterium gains access to an additional carbon source when this gene cluster is expressed. As degradation of sulfonamides was also observed when Microbacterium sp. strain BR1 was grown on artificial urine medium, colonization with such strains may impede common sulfonamide treatment during co-infections with pathogens of the urinary tract. This case of biodegradation exemplifies the evolving catabolic capacity of bacteria, given that sulfonamide bacteriostatic are purely of synthetic origin. The wide distribution of this cluster in Actinomycetes and the presence of traA encoding a relaxase in its vicinity suggest that this cluster is mobile and that is rather alarming.
