Novel pyranochromone derivatives having the general formula: ##STR1## wherein R.sub.1 represents hydrogen atom, an alkali metal or an alkyl group containing 1-4 carbon atoms; R.sub.2, R.sub.3 and R.sub.4 represent hydrogen atom or an alkyl group containing 1-4 carbon atoms respectively, provided that both R.sub.3 and R.sub.4 are not hydrogen atom at the same time; R.sub.5 and R.sub.6 represent an alkyl group containing 1-4 carbon atoms respectively; and R.sub.7 represents hydrogen atom, hydroxyl group, an alkyl group containing 1-4 carbon atoms or an alkoxyl group containing 1-4 carbon atoms. The novel medicaments comprising predominantly the above derivative are effective for the treatment of allergic diseases.

The present invention relates to compositions which inhibit the binding of nerve growth factor to the p75
NTR
common neurotrophin receptor and methods of use thereof. In one embodiment, the compound which inhibits binding of nerve growth factor to p75
NTR
comprises, particularly when bound to nerve growth factor, at least two of the following: (1) a first electronegative atom or functional group positioned to interact with Lys
34
of nerve growth factor; (2) a second electronegative atom or functional group positioned to interact with Lys
95
of nerve growth factor; (3) a third electronegative atom or functional group positioned to interact with Lys
88
of nerve growth factor; (4) a fourth electronegative atom or functional group positioned to interact with Lys
32
of nerve growth factor; and (5) a hydrophobic moiety which interacts with the hydrophobic region formed by Ile
31
, Phe
101
and Phe
86
of nerve growth factor.
A structural material formable at low temperature, prepared by mixing a porous material with a methylol compound which acts as a binder and excipient, a resorcinol compound and/or a precondensate comprising the resorcinol compound and formaldehyde. The methylol group of the methylol compound reacts with the resorcinol compound and/or the precondensate at low temperature in a a short period of time to cause curing. Accordingly, a structural material of this invention can be formed at low temperature.
