Fig. 9 in Design and chemical synthesis of root gravitropism inhibitors: Bridged analogues of ku-76 have more potent activity

Fig. 9. Inhibitory activity tests of gravitropic bending (left) and elongation (right) for naphthyl analogues (a) ku-76, (b) 1a and (c) 1b. 1a completely inhibited elongation at 5 and 50 μM. Data for gravitropic bending and elongation represent mean ± SD. Asterisk indicates statistically significant differences between treatments and controls at p <0.05 (Dunnett's test, n = 7).
