- Identifying Lysophosphatidic Acid Acyltransferase β (LPAAT-β) as the Target of a Nanomolar Angiogenesis Inhibitor from a Phenotypic Screen Using the Polypharmacology Browser PPB2
-
By screening a focused library of kinase inhibitor analogues in a phenotypic co-culture assay for angiogenesis inhibition, we identified an aminotriazine that acts as a cytostatic nanomolar inhibitor. However, this aminotriazine was found to be completely inactive in a whole-kinome profiling assay. To decipher its mechanism of action, we used the online target prediction tool PPB2 (http://ppb2.gdb.tools), which suggested lysophosphatidic acid acyltransferase β (LPAAT-β) as a possible target for this aminotriazine as well as several analogues identified by structure–activity relationship profiling. LPAAT-β inhibition (IC50 ≈15 nm) was confirmed in a biochemical assay and by its effects on cell proliferation in comparison with a known LPAAT-β inhibitor. These experiments illustrate the value of target-prediction tools to guide target identification for phenotypic screening hits and significantly expand the rather limited pharmacology of LPAAT-β inhibitors.

- BIGUANIDE COMPOUND AND USE THEREOF
-
The present invention relates to a guanidine compound and a use thereof, and more specifically, to a guanidine derivative showing excellent effects of inhibiting cancer cell proliferation, cancer metastasis, and cancer recurrence; a preparation method thereof; and a pharmaceutical composition containing the same as an active ingredient. Compared to existing drugs, the guanidine derivative according to the present invention shows excellent effects of inhibiting cancer cell proliferation, cancer metastasis, and cancer recurrence even with small doses, and may thus be effectively used in preventing or treating various cancers such as uterine cancer, breast cancer, stomach cancer, brain cancer, rectal cancer, colorectal cancer, lung cancer, skin cancer, blood cancer, liver cancer, etc., inhibiting cancer cell proliferation and cancer metastasis.

- Synthesis and antiviral activity of benzimidazolyl-and triazolyl-1,3,5- triazines
-
A novel series of 1,3,5-triazine analogs was successfully synthesized through conjugation with benzimidazole or 1,2,4-triazole derivatives via a methylenethio linker. The new analogs were in vitro evaluated against HSV-1 in Vero cells; among these analogs, two compounds exhibited good effect in inhibiting HSV-1 replication (for compound 5p: EC50 = 3.5 μg/ml, SI = 358; for compound 5r: EC50 = 5.0 μg/ml, SI = 300) in comparison to acyclovir.

- High yielding microwave-assisted synthesis of 2-(arylmethyl)amino-4-arylamino-6-alkyl-1,3,5-triazines
-
An efficient and practical procedure was developed to prepare novel 2-(arylmethyl)amino-4-arylamino-6-alkyl-1,3,5-triazines, starting from dicyandiamide and the corresponding arylamines under microwave irradiation and its scope is demonstrated with a number of examples. The valuable feature of this procedure included the short reaction times, high yields, and easy operation.

- Synthesis and in vitro evaluation of 2,4-diamino-1,3,5-triazine derivatives as neuronal voltage-gated sodium channel blockers
-
Neuronal sodium channels blockers interfere with ion flux and have been used for managing neuropathic pain, epilepsy, and cerebral ischemic disorders. In the current study, four groups of 2,4-diamino-1,3,5-triazine derivatives were synthesized and investigated for their neuronal sodium channels binding activity. 5-Aryl-1,3,5-triazaspiro[5.5]undeca-1,3-diene-2,4-diamines (4a-4j) were found to have the best neuronal sodium binding activity among the four groups of triazines evaluated. Derivatives 4a-4j blocked the sodium channels with IC50 values ranged from 4.0 to 14.7 μM. The result from this study showed that analogues of 2,4-diamino-1,3,5-triazines could be used as leads for the discovery of neuronal sodium channels blockers for managing central nervous system related disorders.
