Influence of a Basic Side Chain on the Properties of Hypoxia-Selective Nitro Analogues of the Duocarmycins: Demonstration of Substantial Anticancer Activity in Combination with Irradiation or Chemotherapy

A new series of nitro analogues of the duocarmycins was prepared and evaluated for hypoxia-selective anticancer activity. The compounds incorporate 13 different amine-containing side chains designed to bind in the minor groove of DNA while spanning a wide range of base strength from pKa 9.64 to 5.24. The most favorable in vitro properties were associated with strongly basic side chains, but the greatest in vivo antitumor activity was found for compounds containing a weakly basic morpholine. This applies to single-agent activity and for activity in combination with irradiation or chemotherapy (gemcitabine or docetaxel). In combination with a single dose of γ irradiation 50 at 42 μmol/kg eliminated detectable clonogens in some SiHa cervical carcinoma xenografts, and in combination with gemcitabine using a well-tolerated multidose schedule, the same compound caused regression of all treated A2780 ovarian tumor xenografts. In the latter experiment, three of seven animals receiving the combination treatment were completely tumor free at day 100.

3,5-Bis(benzylidene)-4-piperidones and related N-acyl analogs: A novel cluster of antimalarials targeting the liver stage of Plasmodium falciparum

Drug resistance is a major challenge in antimalarial chemotherapy. In addition, a complete cure of malaria requires intervention at various stages in the development of the parasite within the host. There are only a few antimalarials that target the liver stage of the Plasmodium species which is an essential part of the life cycle of the malarial parasite. We report a series of antimalarial 3,5-bis(benzylidene)-4-piperidones and related N-acyl analogs 1-5, a number of which exhibit potent in vitro growth-inhibiting properties towards drug-sensitive D6 and drug-resistant C235 strains of Plasmodium falciparum as well as inhibiting the liver stage development of the malarial life cycle. The compounds 2b (IC50: 165 ng/mL), 3b (IC50: 186 ng/mL), 5c (IC50: 159 ng/mL) and 5d (IC50: 93.5 ng/mL) emerged as lead molecules that inhibit liver stage Plasmodium berghei and are significantly more potent than chloroquine (IC50: >2000 ng/mL) and mefloquine (IC50: >2000 ng/mL) in this screen. All the compounds that showed potent inhibitory activity against the P. berghei liver stage were nontoxic to human HepG2 liver cells (IC50: >2000 ng/mL). The compounds 5a and 5b exhibit comparable metabolic stability as chloroquine and mefloquine in human plasma and the most potent compound 5d demonstrated suitable permeability characteristics using the MDCK monolayer. These results emphasize the value of 3,5-bis(benzylidene)-4-piperidones as novel antimalarials for further drug development.

Falcipain inhibitors: Optimization studies of the 2-pyrimidinecarbonitrile lead series

Falcipain-2 and falcipain-3 are papain-family cysteine proteases of the malaria parasite Plasmodium falciparum that are responsible for host hemoglobin hydrolysis to provide amino acids for parasite protein synthesis. Different heteroarylnitrile derivatives were studied as potential falcipain inhibitors and therefore potential antiparasitic lead compounds, with the 5-substituted-2- cyanopyrimidine chemical class emerging as the most potent and promising lead series. Through a sequential lead optimization process considering the different positions present in the initial scaffold, nanomolar and subnanomolar inhibitors at falcipains 2 and 3 were identified, with activity against cultured parasites in the micromolar range. Introduction of protonable amines within lead molecules led to marked improvements of up to 1000 times in activity against cultured parasites without noteworthy alterations in other SAR tendencies. Optimized compounds presented enzymatic activities in the picomolar to low nanomolar range and antiparasitic activities in the low nanomolar range.

Design, synthesis and cytotoxic properties of novel 1-[4-(2-alkylaminoethoxy)phenylcarbonyl]-3,5-bis(arylidene)-4-piperidones and related compounds

The 3,5-bis(arylidene)-4-piperidones 1 contain the 1,5-diaryl-3-oxo-1,4-pentadienyl pharmacophore which is considered to interact at a complementary binding site in susceptible neoplasms. The hypothesis was formulated that the presence of an acyl group attached to the piperidyl nitrogen atom in series 1 may interact with an additional binding site thereby enhancing cytotoxic potencies. This concept led to the synthesis of various N-acyl-3,5-bis(arylidene)-4-piperidones 3-7 many of which displayed significant cytotoxicity towards a variety of cancer cell lines. A comparison of the potencies between the compounds in series 1 and the related nonquaternary analogues 3-6 revealed that in approximately half of the comparisons made, the N-acyl analogues had increased potencies.
