small molecule gibberellin JRA-003 was identified as an inhibitor of the NF-kB (nuclear kappa-light-chain-enhancer of activated B cells) pathway. Here we find that JRA-003 binds to and significantly inhibits the nuclear translocation of pathway-activating kinases IKKα (IκB kinase alpha) and IKKβ (IκB kinase beta). Analogs of JRA-003 were synthesized and NF-κB-inhibiting gibberellins were found to be

17-double bonds in some derivatives of ent-gibberellane were unsuccessful except in the case of allogibberic acid (VIII; 9α-H, R = H) and its methyl ester (VIII; 9α-H, R = Me), which reacted at the 16,17-double bond to give the expected 15-en-17-ols (IX; R = H) and (IX; R = Me), respectively. Acid-catalysed rearrangement of the latter (IX; R = Me) gave the hydroxymethyl derivative (X; R = Me) of methyl
在某些ent- gibberellaellane衍生物中尝试对2,3-和16,17-双键进行光氧合是成功的,但别的是用脲基酸(VIII;9α-H,R = H)及其甲基酯(VIII) ;9α-H,R = Me),其在16,17-双键处反应分别得到预期的15-en-17-ols(IX; R = H)和(IX; R = Me)。后者的酸催化重排(IX; R = Me)得到了赤霉素甲酯的羟甲基衍生物(X; R = Me),与从赤霉素A 3 16,17-环氧化物获得的重排产物的甲酯相同(XI; R = H)。来自脲醛酸甲酯的光氧合产物的重排的主要产物是15-羟基阿糖酸的7→15-内酯(XIII)。

Synthesis and anti-proliferative activity of allogibberic acid derivatives containing 1,2,3-triazole pharmacophore
allogibberic acid derivatives containing 1,2,3-triazole pharmacophore were designed and synthesized. The key chemical processes include aromatization of the A ring in gibberellins, formation of allogibberic azides and its copper mediated Huisgen 1,3-dipolar cycloaddition with alkynes. A number of hybrids containing α,β-unsaturated ketone moiety exhibited excellent in vitro cytotoxic activities. Some of the hybrids
