(Table presented.). A new series of 1,3-dimethylxanthine derivatives bearing 8-(2-nitroaryl) residue was synthesized and evaluated for affinity for recombinant human adenosine receptors subtypes. Nitrate esters of 7-substituted-1,3-dimethyl-8-phenylxanthines were also synthesized and tested. Introducing a nitro substituent at the 2-position of the 8-substituted phenyl ring resulted in generally low affinity for adenosine receptors (ARs), selectivity toward the A2A subtype was enhanced in some of the compounds. 8-(4-Cyclopentyloxy-5-methoxy-2-nitrophenyl)-1,3-dimethylxanthine (9e) proved to be a potent compound among the 2-nitrophenyl substituted xanthines exhibiting a Ki = 1 μM at human A2A ARs with at least 30 fold selectivity versus human A1 and A2B ARs. Replacement of 8-chloropropoxy phenyl with 8-nitrooxypropoxy phenyl resulted in a negligible change in binding affinity of the 8-substituted xanthines for various AR subtypes.

-
, (2017/07/01)
The invention discloses a 2-indolone derivative with tyrosine kinase inhibition activity, geometric isomers and medicinal salts thereof, and a preparation method and an application of the above compounds. Tyrosine kinase inhibition activity evaluation confirms that the derivative is a compound with good tyrosine kinase activity, so the derivative has potential antitumor activity, and can be used to prepare tumor disease prevention and treatment medicines (antitumor medicines) as an active component. The derivative provides research and enforcement foundation for tumor treatment, and has a wide application prospect.

A series of novel monocarbonyl analogues of curcumin have been designed, synthesized and tested for their activity against Molt4, HeLa, PC3, DU145 and KB cancer cell lines. Six of the analogues showed potent cytotoxicity towards these cell lines with IC50 values below 1 μM, which is better than doxorubicin, a US FDA approved drug. Several analogues were also found to be active against both CQ-resistant (W2 clone) and CQ-sensitive (D6) strains of Plasmodium falciparum in an in-vitro antimalarial screening. This level of activity warrants further investigation of the compounds for development as anticancer and antimalarial agents.

experimental part, p. 5965 - 5978 (2011/01/13)
A series of [4-(aryloxy)phenyl]cyclopropyl methanones were synthesized by reaction of different benzyl alcohols with 4-chloro-4′-fluorobutyrophenone in DMF in the presence of NaH/TBAB. The methanones were further reduced to respective methanols. The antitubercular activity of these compounds was evaluated in vitro against Mycobacterium tuberculosis H37Rv. Compounds 19, 21, 35, 36 and 37 have shown minimum inhibitory concentration (MIC) of 3.12 μg/mL, while compounds 14, 25 and 18 have shown MIC of 1.56 μg/mL and 0.78 μg/mL respectively. One of the compounds, cyclopropyl-4-[4-(2-piperidin-1- yl-ethoxy)benzyloxy]phenyl}methanol (36) showed 98% killing of intracellular bacilli in mouse bone marrow derived macrophages and was active against MDR, XDR and rifampicin clinical isolates resistant strains with MIC 12.5 μg/mL. Compound 36 was orally active in vivo in mice against M. tuberculosis H37Rv with an increase in MST by 6 days with 1 log reduction in the bacillary density in lungs as compared to control on 30th day after infection.

experimental part, p. 2122 - 2127 (2009/09/30)
A new series of 8-(substituted-phenyl)xanthines have been synthesized and compounds were evaluated for their affinity for A1 and A2 adenosine receptors (AR) using radioligand binding assays. The effects of varying the positions of 8-phenyl substituents on affinity and selectivity at A1 and A2A adenosine receptors have been studied. Isovanilloid 1,3-dimethyl-8-[4-methoxy-3-(2-morpholin-4-ylethoxy)phenylxanthine (9d) displayed the highest affinity and selectivity towards A2A AR subtypes with Ki = 100 nM over A1 receptors (Ki > 100 mM). It has been observed that substitution pattern on 8-phenyl group greatly affects the affinity and selectivity at adenosine receptors, with A2A tolerating bulkier substituents than did A1 receptors.

Novel analogs of trifenagrel were synthesized by using inexpensive and reusable phosphotungstic acid, H3[PW12O40] (3 mol %) catalyst under classical heating. Two of the newly synthesized triaryl imidazoles exhibited moderate antibacterial activity.

experimental part, p. 1391 - 1399 (2009/04/06)
The synthesis and cytotoxic studies of a new series of 16E-arylidene androstene derivatives are reported herein. The impact of incorporating bis-tertiary amino functionalities in the steroid skeleton on cytotoxicity has also been observed. The compounds have been evaluated at National cancer Institute, Bethesda, Maryland, USA for their antineoplastic activity against various tumor cell lines. The synthesized 16E-arylidenosteroids exhibited significant cytotoxicity. Bis-tertiary amino steroid 29 possessing a diethylaminoalkoxy functionality was the most promising compound of the series with a total IP and SC score of 20 in in vivo hollow fiber assay and was selected for further detailed in vivo xenograft testing.
