The identification and lead optimization of a series of pyridopyrimidinone derivatives are described as a novel class of efficacious dual PI3K/mTOR inhibitors, resulting in the discovery of 31. Compound 31 exhibited high enzyme activity against PI3K and mTOR, potent suppression of Akt and p70s6k phosphorylation in cell assays, and good pharmacokinetic profile. Furthermore, compound 31 demonstrated in vivo efficacy in a PC-3M tumor xenograft model.

Tropical protozoal infections are a significant cause of morbidity and mortality worldwide; four in particular (human African trypanosomiasis (HAT), Chagas disease, cutaneous leishmaniasis, and malaria) have an estimated combined burden of over 87 million disability-adjusted life years. New drugs are needed for each of these diseases. Building on the previous identification of NEU-617 (1) as a potent and nontoxic inhibitor of proliferation for the HAT pathogen (Trypanosoma brucei), we have now tested this class of analogs against other protozoal species: T. cruzi (Chagas disease), Leishmania major (cutaneous leishmaniasis), and Plasmodium falciparum (malaria). Based on hits identified in this screening campaign, we describe the preparation of several replacements for the quinazoline scaffold and report these inhibitors' biological activities against these parasites. In doing this, we have identified several potent proliferation inhibitors for each pathogen, such as 4-((3-chloro-4-((3-fluorobenzyl)oxy)phenyl)amino)-6-(4-((4-methyl-1,4-diazepan-1-yl)sulfonyl)phenyl)quinoline-3-carbonitrile (NEU-924, 83) for T. cruzi and N-(3-chloro-4-((3-fluorobenzyl)oxy)phenyl)-7-(4-((4-methyl-1,4-diazepan-1-yl)sulfonyl)phenyl)cinnolin-4-amine (NEU-1017, 68) for L. major and P. falciparum.

The invention relates to the use of cinnoline derivatives of formula (I) wherein Z represents —O—, —NH—, —S— or —CH2—; m is a n integer from 1 to 5; R1represents hydrogen, hydroxy, halogeno, nitro, cyano, trifluoromethyl, Cp1-3alkyl, C1-3alkoxy, C1-3alkylthio or NR6R7(wherein R6and R7, which may be the same or different, each represents hydrogen or C1-3alkyl); R2represents hydrogen, hydroxy, auoro, chioro, methoxy, amino or nitro; R3represents hydroxy, halogeno, C1-3alkyl, C1-3alkoxy, C1-3alkanoyloxy, trifluoromethyl, cyano, amino or nitro; R4represents hydrogen, hydroxy, halogeno, cyano, nitro, amino, trifluoromethyl, C1-3alkyl or a group R5—X1(wherein X1represents —O—, —CH2—, —S—, —SO—, —SO2—, —NR8CO—, —CONR9—, —SO2NR10—, —NR11SO2— or NR12— (wherein R8, R9, R10, R11and R12each independently represents hydrogen, C1-3alkyl or C1-3alkoxy C2-3alkyl) and R5is an optionally substituted alkyl, carbocylic or heterocylic group which may be saturated or unsaturated and may be directly linked to the cinnoline ring or be linked via a carbon chain which may have heteroatom linking groups within it and salts thereof, in the manufacture of a medicament for use in the production of an anti angiogenic and/or vascular permeability reducing effect in a warmn-blooded animal such as a human being, processes for the preparation of such derivatives, pharmnaceutical compositions containing a compound of formula (I) or a pharmnaceutically acceptable salt thereof as active ingredient and compounds of formula (I). The compounds of formula (I) and the pharmaceutically acceptable salts thereof inhibit the effects of VEGF, a property of value in the treatment of a number of disease states including cancer and rheumatoid arthritis.
