Madindoline A
Madindoline A is an orally active gp130 antagonist with a KD of 288 μM. Madindoline A inhibits IL-6- and IL-11-induced osteoclastogenesis, suppresses IL-6-stimulated serum amyloid A protein production, inhibits bone resorption and bone loss, and also inhibits IL-6- and IL-11-dependent cell line growth, as well as IL-6-dependent Stat3 tyrosine phosphorylation. Madindoline A is applicable for the research of hormone-dependent postmenopausal osteoporosis.

Madindoline A (0.5-70 μM; 72 h) acts as a competitive and selective antagonist of IL-6 responses in IL-6-dependent MH-60 cells, with a pA2 value of 4.78. It does not affect cell growth mediated by IL-2, IL-3 or TNF, nor does it influence cell growth under non-IL-6-dependent conditions[1].
Madindoline A (70 μM; 72 h) significantly inhibits IL-6-induced differentiation of M1 cells into macrophage-like cells, but does not affect basal differentiation or LIF-induced differentiation[1].
Madindoline A (100 μM; 15 min) inhibits IL-6-induced tyrosine phosphorylation of STAT3 in HepG2 cells, but does not affect LIF-induced STAT3 phosphorylation[1].
Madindoline A (30 μM; 4 days) significantly inhibits osteoclast formation induced by IL-6 and IL-11 in a co-culture system of mouse calvarial osteoblasts and bone marrow cells, but exerts no effect on osteoclast formation induced by LIF, IL-1, or 1α,25 (OH) 2D3[1].

Cell Line:IL-6-dependent MH-60 cells; IL-2-dependent CTLL-2 cells; IL-3-dependent Baf3 cells; TNF-sensitive L929 cells; IL-6-independent MH-60 cells
-
Concentration:0.5, 1.75, 3.5, 7, 17.5, 35, 70 μM
-
Incubation Time:72 h
-
Result:Did not alter growth of IL-2-dependent CTLL-2 cells, IL-3-dependent Baf3 cells, or TNF-sensitive L929 cells, nor inhibit growth of IL-6-independent MH-60 cells.
Dose-dependently suppressed IL-6-induced cell growth of IL-6-dependent MH-60 cells and caused parallel rightward shifts of IL-6 dose-response curves.
Yielded a pA2 value of 4.78 and a slope of 0.99 via Schild plot analysis, confirming competitive antagonism.
-
Cell Line:M1 cells
-
Concentration:70 μM (pre-incubation with IL-6)
-
Incubation Time:72 h (pre-incubation with IL-6); 24 h (bead incubation)
-
Result:Significantly decreased the population of differentiated macrophage-like cells induced by IL-6.
Did not alter differentiation status relative to untreated cells when used alone.
Madindoline A (60 mg/kg; p.o.; once every other day; for 4 weeks) significantly inhibits bone resorption and bone loss in ovariectomized mice without affecting their uterine weight or serum IL-6 levels[1].

-
Dosage:10 mg/kg; 60 mg/kg
-
Administration:p.o.; single dose
-
Result:Reduced IL-6-induced serum amyloid A (SAA) levels to 34.7 ng/mL.
Reduced IL-6-induced serum amyloid A (SAA) levels to 16.3 ng/mL.

Animal Model:ddY (4-week-old female; postmenopausal osteoporosis induced by bilateral ovariectomy)[1]
-
Dosage:10 mg/kg; 60 mg/kg
-
Administration:p.o.; every other day; 4 weeks
-
Result:Did not produce significant changes in measured parameters (bone mass, serum calcium, uterine weight, serum IL-6 levels).
Significantly suppressed ovariectomy-induced bone loss, resulting in a bone mass ratio of 1.92.
Reduced serum calcium levels to 11.3 mg/dL.
Did not alter uterine weight or serum IL-6 levels.
