26593832-7	2012	We compared the binding affinity to N2 with various carbenes (:CF2, :CCl2, :CBr2, and :CI2).	Nitrogen	36-38	C-C motif chemokine ligand 2	Homo sapiens	69-73	
33561155-11	2021	The highly intensified receptor interaction of BPC is attributable to the presence of an n-pi-pi-n conjugation system mediated through the >C = CCl2 double bond.	Nitrogen	12-13	C-C motif chemokine ligand 2	Homo sapiens	144-148	
33561155-11	2021	The highly intensified receptor interaction of BPC is attributable to the presence of an n-pi-pi-n conjugation system mediated through the >C = CCl2 double bond.	Nitrogen	15-16	C-C motif chemokine ligand 2	Homo sapiens	144-148	
26022021-12	2015	Urinary MCP-1 correlates positively with proteinuria, blood urea nitrogen level and creatinine and negatively with hemoglobin and creatinine clearance.	Nitrogen	65-73	C-C motif chemokine ligand 2	Homo sapiens	8-13	
24600221-8	2014	The rapid decrease of blood creatinine, urine creatinine, and blood urea nitrogen suggested that the recovery of renal functions compromised by hyperglycemia could also be attributed to MCP-1.	Nitrogen	73-81	C-C motif chemokine ligand 2	Homo sapiens	186-191	
34850458-6	2022	The shifting and intensity enhancement of the CCl2 band manifests the back-donation and conjugation effect, which are the result of the presence of nitrogen atom adjoining the dichloromethyl groups and the oxygen in the sulfur dioxide group attached among the amino group and the chlorophenyl ring, respectively, which enhances bioactivity.	Nitrogen	148-156	C-C motif chemokine ligand 2	Homo sapiens	46-50	
16735126-6	2006	These data suggest that 2-O and N sulfation of heparin may be of greater importance to CCL2-heparin binding than 6-O sulfation.	Nitrogen	32-33	C-C motif chemokine ligand 2	Homo sapiens	87-91	
10484461-0	1999	Effects of reactive oxygen and nitrogen metabolites on MCP-1-induced monocyte chemotactic activity in vitro.	Nitrogen	31-39	C-C motif chemokine ligand 2	Homo sapiens	55-60
