In the quest for potent antiamoebic agents, a series of hydrazone hybrids (H1[sbnd]H30) have been designed and sequentially synthesized. The dimethylaminoethoxy and hydrazone entities incorporated into one molecule proved to be more persuasive and selecti

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.

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.

In an effort to prepare nonsteroidal antiestrogens demonstrating greater antagonism and less intrinsic estrogenicity than those currently available, a series of 3-aroyl-2-arylbenzothiophene derivatives was synthesized.These compounds were prepared by Friedel-Crafts aroylation of appropriate O-protected 2-arylbenzothiophene nuclei with basic side-chain-bearing benzoyl chlorides followed by removal of the protective groups to provide the desired compounds containing both hydroxyl and basic side-chain functionality.A particularly useful method for the cleavage of aryl methoxy ethers without removal of (dialkylamino)ethoxy side chain functionality elsewhere in the molecule was found to be AlCl3/EtSH.The benzothiophene derivatives were tested for their ability to inhibit the growth-stimulating action of estradiol on the immature rat uterus.Seemingly minor changes in the side-chain amine moiety were found to have profound effects on the ability of the compounds to antagonize estradiol.Analogues having basic side chains containing cyclic (pyrrolidine, piperidine, and hexamethyleneamine) moieties were found to have less intrinsic estrogenicity and to antagonize estradiol action more completely than their noncyclic counterparts.The most effective antiestrogen in the series, compound 44, thien-3-yl>phenyl>methanone, elicited a modest uterotropic activity that did not increase with increasing dose.In antagonism of estradiol, 44 exhibited a degree of inhibition surpassing that of tamoxifen at any dose tested.The new benzothiophene antiestrogen was also shown to have high affinity for rat uterine cycloplasmic estrogen receptor and to be an inhibitor of the growth of DMBA-induced rat mammary tumors.
