Anti-HIV-1 and -HIV-2 activity and cytostatic properties of Clematis montana lectin (CML) in human T-lymphocyte (CEM) cells.

Compound	EC50 (μg/ml)		CC50 (μg/ml)
	HIV-1	HIV-2
CML	11 ± 3.9	71 ± 41	>100
GNA	0.92	0.78	6.9
LRA	0.79	0.59	7.1
SCA	4.6	8	83

GNA, Galanthus nivalis agglutinin; LRA, Lycoris radiate agglutinin; SCA, Scilla campanulata agglutinin [42].

EC₅₀ = effective concentration or concentration required to protect CEM cells against the cytopathogenicity of HIV by 50%.

CC₅₀ = cytotoxic concentration or concentration required to reduce CEM cell viability by 50%.
