Examples of the department's scientific developments

Synthesis of pyrrolo [2,3-d] pyrimidine derivatives with 3-amino-2-hydroxypropyl substituents (Verves EV, Muzychka LV)

Pyrrolo[2,3-d] pyrimidine derivatives with a carboxyl group at position 6 of the heterocycle proved to be valuable reagents for introducing 2,3-epoxypropyl and 3-amino-2-hydroxypropyl substituents to the nitrogen atom of the pyrrole ring.

In the treatment of bromomethylpyrimido [5 ′, 4 ′: 4,5] pyrrolo [2,1-c] [1,4] oxazine 2 with sodium methylate we obtained ethyl ester of 7-oxyranylmethyl-1H-pyrrolo [2,3-d] pyrimidine-6-carboxylic acids 8. Based on the glycidyl derivative of pyrrolo [2,3-d] pyrimidine 8, a number of representatives of new heterocyclic systems were synthesized - pyrimido [5 ′, 4 ′: 4,5] pyrrolo [1,2-a] [1,4] diazepine 7 and pyrimido [5 ′, 4 ′: 4,5] pyrrolo [2,1-c] [1,4] oxazine 9.
Investigation of the interaction of substrates 2, 8 with aliphatic amines has shown the possibility of using these compounds to obtain pyrrolo [2,3-d] pyrimidine derivatives containing 3-amino-2-hydroxypropyl substituents at position 7 of the heterocycle.

The docking results of some of the compounds obtained indicate the prospects of finding among them effective antagonists of adenosine receptors.

Synthesis of new 7-deazapurine derivatives with alkylphosphoryl substituents (Yaremchuk IO, Muzychka LV)

The development of methods for the synthesis of heterocyclic compounds with phosphorus-containing substituents is associated with the prospect of finding antiviral drugs among them. Particular attention is drawn to beta-hydroxyphosphonates, structural analogues of adefovir (PMEA).
Нами запропонований новий підхід до синтезу фосфорильованих похідних піроло[2,3-d]піримідину. Вихідною сполукою був вибраний 8-бромометилпіримідо[5′,4′:4,5]піроло[2,1-с][1,4]оксазин, котрий виявився перспективним реагентом для отримання бета-гідроксифосфонових кислот. За допомогою нескладних перетворень отримані похідні піроло[2,3-d]піримідину з 1-гідроксифосфоноетильним замісником в 7 положенні гетероциклічної системи.

Модифікація піримідо[5′,4′:4,5]піроло[2,1-с][1,4]оксазинового циклу привела до нових похіднихпіразино[1′,2′:1,5]піроло[2,3-d]піримідину з алкілфосфорильними замісниками.

Synthesis of new pyrido [2,3-d]pyrimidin-7-one derivatives (GM Zinchenko, LV Muzychka)

Significant interest in the chemistry of pyrido [2,3-d] pyrimidines is due in recent years to the discovery of selective tyrosine kinase inhibitors, among them, promising targets for the creation of anticancer drugs. Despite the considerable advances in the synthesis of pyrido [2,3-d] pyrimidine derivatives, the search for preparative methods for introducing functional groups into certain positions of the heterocyclic ring remains an urgent task.

On the basis of 4,6-dichloro-5-formylpyrimidine, a convenient approach to the synthesis of novel pyrido [2,3-d] pyrimidin-7-one 1-6 derivatives containing various nitrogen-containing substituents at positions 4, 6, 7 of the heterocyclic system has been developed. The study of the interaction of 4,6-dichloropyrimidine-5-carbaldehyde with glycine esters led to the development of a one-pot method for obtaining two condensed systems - pyrido [2,3-d] pyrimidine and pyrrolo [2,3-d] pyrimidine. Further modification of the synthesized compounds opens the possibility of obtaining promising pyrido [2,3-d] pyrimidine derivatives for the search for new bioactive substances.

Synthesis and study of the properties of tricyclic compounds with a 1,3-dimethyluracil nucleus (Biletsky II, LV Muzychka)

Of particular interest is the design and synthesis of heterocyclic compounds containing pharmacophores of different heterocyclic nature in their structure. Given the high synthetic potential of pyrimidine derivatives, it remains relevant to design heterocyclic systems that would contain various combinations of pyrimidine nuclei with other heterocyclic systems. Due to the possibility of variation of substituents or additional heterocyclic fragments, they are able to exhibit a wide range of pharmacological activity. Condensed heterocyclic compounds containing the 1,3-dimethyluracil nucleus are promising in this regard.

Based on 1,3-dimethyl-5-formyl-6-chlorouracil, a simple approach to the synthesis of tricyclic compounds 2-7 has been developed. New pyrimido [4,5-b] quinoline-2,4(1H,3H) -dione (5-deazaaloxazine), pyrimido [4,5-b] -1,5-naphthyridine-2,4(1H, 3H) -dione and pyrimido [4,5-b]-1,7-naphthyridine-2,4 (1H, 3H) -dione, and pyrazolo [4′,3′: 5,6] pyrido [2,3-d]pyrimidine. The structure of the intermediate products of the cyclization reaction of 6-arylamino-5-formyluracil in 5-deazaaloxazines was investigated. Cyclocondensation of 1,3-dimethyl-5-formyl-6-chlorouracil with substituted 2-, 3-aminopyridines and 3-, 4-, 5-aminopyrazoles was studied.

A simple method for the synthesis of quinoline, naphthyridine, pyrazolo [3,4-b] pyridine derivatives with methylamide and methylamine substituents by the hydrolytic cleavage of the pyrimidine cycle is developed.
