Anthranilamide-based 2-phenylcyclopropane-1-carboxamides, 1,1'-biphenyl-4-carboxamides and 1,1'-biphenyl-2-carboxamides: Synthesis biological evaluation and mechanism of action

Several anthranilamide-based 2-phenylcyclopropane-1-carboxamides 13a-f, 1,1’-biphenyl-4-carboxamides 14a-f and 1,1’-biphenyl-2-carboxamides 17a-f were obtained by a multistep procedure starting from the (1S,2S)-2-phenylcyclopropane-1-carbonyl chloride 11, the 1,1'-biphenyl-4-carbonyl chloride 12 or the 1,1'-biphenyl-2-carbonyl chloride 16 with the appropriate anthranilamide derivative 10a-f. Derivatives 13a-f, 14a-f and 17a-f showed antiproliferative activity against human leukemia K562?cells. Among these derivatives 13b, 14b and 17b exerted a particular cytotoxic effect on tumor cells. Derivative 17b showed a better antitumoral effect on K562?cells than 13b and 14b. Analyses performed to explore 17b mode of action revealed that it induced an arrest in G2/M phase of cell cycle which was consequent to DNA lesions as demonstrated by the increase in phospho-ATM and γH2AX, two known markers of DNA repair response system. The effect of 17b was also related to ROS generation, activation of JNK and induction of caspase-3 dependent apoptosis.

Property Focused Structure-Based Optimization of Small Molecule Inhibitors of the Protein-Protein Interaction between Menin and Mixed Lineage Leukemia (MLL)

Development of potent small molecule inhibitors of protein-protein interactions with optimized druglike properties represents a challenging task in lead optimization process. Here, we report synthesis and structure-based optimization of new thienopyrimidine class of compounds, which block the protein-protein interaction between menin and MLL fusion proteins that plays an important role in acute leukemias with MLL translocations. We performed simultaneous optimization of both activity and druglike properties through systematic exploration of substituents introduced to the indole ring of lead compound 1 (MI-136) to identify compounds suitable for in vivo studies in mice. This work resulted in the identification of compound 27 (MI-538), which showed significantly increased activity, selectivity, polarity, and pharmacokinetic profile over 1 and demonstrated a pronounced effect in a mouse model of MLL leukemia. This study, which reports detailed structure-activity and structure-property relationships for the menin-MLL inhibitors, demonstrates challenges in optimizing inhibitors of protein-protein interactions for potential therapeutic applications.

Synthesis, antiproliferative activity and possible mechanism of action of novel 2-acetamidobenzamides bearing the 2-phenoxy functionality

Several new 2-(2-phenoxyacetamido)benzamides 17a-v, 21 and 22 were synthesized by stirring in pyridine the acid chlorides 16a-e and the appropriate5-R-4-R1-2-aminobenzamide 15a-e and initially evaluated in vitro for antiproliferative activity against the K562 (human chronic myelogenous leukemia) cell line. Some of synthesized compounds were evaluated for their in vitro antiproliferative activity against the full NCI tumor cell line panel derived from nine clinically isolated cancer types (leukemia, non-small cell lung, colon, CNS, melanoma, ovarian, renal, prostate and breast). The most active compounds caused an arrest of K562 cells in the G0-G1 phase of cell cycle and induction of apoptosis, which was mediated by caspase activation.

SUBSTITUTED 2- AMIDOQUINAZOL-4-ONES AS MATRIX METALLOPROTEINASE-13 INHIBITORS

The present invention provides a novel amide derivative having a matrix metalloproteinase inhibitory activity, and useful as a pharmaceutical agent, which is a compound represented by the formula (I) wherein ring A is an optionally substituted, nitrogen containing heterocycle, ring B is an optionally substituted monocyclic homocycle or an optionally substituted monocyclic heterocycle, Z is N or NR1 (R1 is a hydrogen atom or an optionally substituted hydrocarbon group), is a single bond or a double bond, R2 is a hydrogen atom or an optionally substituted hydrocarbon group, X is an optionally substituted spacer having 1 to 6 atoms, ring C is (1) an optionally substituted homocycle or (2) an optionally substituted heterocycle other than a ring represented by (II) (X′ is S, O, SO, or CH2), and at least one of ring B and ring C has substituent(s), provided that N-{(1S,2R)-1-(3,5-difluorobenzyl)-3-[(3-ethylbenzyl)amino]2 hydroxypropyl}5,6 dimethyl 4 oxo 1,4 dihydrothieno[2,3-d]pyrimidine-2-carboxamide is excluded, or a salt thereof.

2-Cinnamamido, 2-(3-phenylpropiolamido), and 2-(3-phenylpropanamido) benzamides: Synthesis, antiproliferativeactivity, and mechanism of action

Several new benzamides 4a-q were synthesized by stirring in pyridine the acid chlorides 3a-q with the appropriate anthranilamide derivatives 2a-g. Some of the synthesized compounds were evaluated for their in vitro antiproliferative activity against a panel of 5 human cell lines (K562 human chronic myelogenous leukemia cells, MCF-7 breast cancer cells, HTC-116 and HT26 colon cancer cells and NCI H460 non-small cell lung cancer cells).

Synthesis, antiproliferative activity, and mechanism of action of a series of 2-{[(2E)-3-phenylprop-2-enoyl]amino}benzamides

Several new 2-{[(2E)-3-phenylprop-2-enoyl]amino}benzamides 12a-s and 17t-v were synthesized by stirring in pyridine the (E)-3-(2-R1-3-R2-4-R3-phenyl) acrylic acid chlorides 11c-k and 11t-v with the appropriate anthranilamide derivatives 10a-c or the 5-iodoanthranilic acid 13. Some of the synthesized compounds were evaluated for their in vitro antiproliferative activity against the full NCI tumor cell line panel derived from nine clinically isolated cancer types (leukemia, non-small cell lung, colon, CNS, melanoma, ovarian, renal, prostate and breast). COMPARE analysis, effects on tubulin polymerization in cells and with purified tubulin, and effects on cell cycle distribution for 17t, the most active of the series, indicate that these new antiproliferative compounds act as antitubulin agents.

Antifolates for the treatment of cardiovascular, inflammatory, neoplastic, autoimmune and related diseases in sublingual dosage units, film strips, or skin patches

New metabolism blocked antifolates and their salts are provided along with new indications (coronary heart disease, cardiovascular diseases, stroke and termination of tubal or ectopic pregnancy) and methods (sublingual dosage forms, filmstrips or patches) for their use and delivery. Sublingual dosage forms or trans-dermal patches of metabolically blocked entities of this invention offer superior alternatives to traditional oral dosage forms to achieve greater and predictable therapeutic efficacy, lower toxicity and to overcome drug resistance by virtue of elimination of oxidative deactivation and production of toxic metabolites. Metabolism blocked antifolates bearing a fluorinated benzene ring, a thiophene ring, a pyrrole ring, a furan ring or a 8-deazapteridine ring that are provided in this invention are not previously described. The use of metabolism blocked antifolates to terminate medically complicated pregnancies that are taught herein are new inventions targeted to eliminate drug related toxicity to the host and to enhance therapeutic efficacy.

Amidation of esters assisted by Mg(OCH3)2 or CaCl2

Magnesium methoxide (Mg(OCH3)2) and calcium chloride have been shown to facilitate the direct aminolysis of esters by ammonia to primary amides. Methyl, ethyl, isopropyl, and tert-butyl esters were converted to the corresponding carboxamides in good yields. Reactions have been run on a larger scale and without the safety liability inherent in the use of magnesium nitride (Mg3N2). Ammonium chloride and amine hydrochlorides have been used successfully in the place of ammonia with magnesium methoxide.
